Abstract:

A combination of solid-state nuclear magnetic resonance (NMR) and first principles calculations was applied to obtain 17O, 25Mg, and 33S NMR parameters for two polymorphs of anhydrous magnesium sulfate. Working at the very high magnetic field of 21.14 T results in a dramatic improvement of resolution through a reduction of the effects of quadrupolar interactions and significant improvement in sensitivity. Experimental 25Mg and 33S spectra are dominated by quadrupolar interactions with quadrupolar parameters unique for each polymorph. In the case of 17O, there is a substantial contribution of the chemical shift anisotropy. The use of multiple-quantum magic-angle spinning (MQMAS) experiments allows the resolution of distinct oxygen species and assignment of signals in the experimental 17O spectrum. Chemical shielding constants and quadrupolar parameters for all three nuclei were calculated using plane wave pseudopotential density functional theory as implemented in the CASTEP computational package. The calculated NMR parameters are in very good agreement with the experimental results and help in signal assignment of the 17O spectrum. The results suggest applicability of such a combined computational and experimental solid-state NMR approach for the refinement of crystallographic data.

Abstract:

A density functional theory (DFT) study of the 1H- and 13C-NMR chemical shifts of the geometric isomers of 18:2 ω-7 conjugated linoleic acid (CLA) and nine model compounds is presented, using five functionals and two basis sets. The results are compared with available experimental data from solution high resolution nuclear magnetic resonance (NMR). The experimental 1H chemical shifts exhibit highly diagnostic resonances due to the olefinic protons of the conjugated double bonds. The “inside” olefinic protons of the conjugated double bonds are deshielded than those of the “outside” protons. Furthermore, in the cis/trans isomers, the signals of the cis bonds are more deshielded than those of the trans bonds. These regularities of the experimental 1H chemical shifts of the olefinic protons of the conjugated double bonds are reproduced very accurately for the lowest energy DFT optimized single conformer, for all functionals and basis sets used. The other low energy conformers have negligible effects on the computational 1H-NMR chemical shifts. We conclude that proton NMR chemical shifts are more discriminating than carbon, and DFT calculations can provide a valuable tool for (i) the accurate prediction of 1H-NMR chemical shifts even with less demanding functionals and basis sets; (ii) the unequivocal identification of geometric isomerism of CLAs that occur in nature, and (iii) to derive high resolution structures in solution.

Abstract:

Abstract The use of 23Na nuclear magnetic resonance with aqueous shift reagent has made it possible to determine intracellular sodium concentrations in living erythrocytes. We applied this technique to samples from 16 healthy subjects and 41 uremic patients. The results seem to show distinct populations among the latter. Classically, two different relaxation times are obtained for intracellular sodium in biological media, according to relaxation NMR theory. Some patients, however, exhibit abnormal results that cannot be accounted for by this theory.

Abstract:

A combination of selective 1D Total Correlation Spectroscopy (TOCSY) and 1H-13C Heteronuclear Multiple Bond Correlation (HMBC) NMR techniques has been employed for the identification of methyl linolenate primary oxidation products without the need for laborious isolation of the individual compounds. Complex hydroperoxides and diastereomeric endo-hydroperoxides were identified and quantified. Strongly deshielded C–O–O–H 1H-NMR resonances of diastereomeric endo-hydroperoxides in the region of 8.8 to 9.6 ppm were shown to be due to intramolecular hydrogen bonding interactions of the hydroperoxide proton with an oxygen atom of the five-member endo-peroxide ring. These strongly deshielded resonances were utilized as a new method to derive, for the first time, three-dimensional structures with an assignment of pairs of diastereomers in solution with the combined use of 1H-NMR chemical shifts, Density Functional Theory (DFT), and Our N-layered Integrated molecular Orbital and molecular Mechanics (ONIOM) calculations.

Abstract:

Thioxo, Oxo and Seleno diastereomeric cyclophosphamides containing 1,3,2- dioxaphosphorinane are prepared by a one-step chemical reaction. Their structural determination is carried out by means of Nuclear Magnetic Resonance NMR (31P, 1 H, 13C) and High-Resolution Mass Spectroscopy (HRMS). The conformational study of diastereomeric products is described. Density Functional Theory (DFT) calculations allowed the identification of preferred conformations. Experimental and calculated 31P, 13C, 1H NMR chemical shifts are compared. The molecular structure of the 2-Benzylamino-5-methyl-5- propyl-2-oxo-1,3,2-dioxaphosphorinane (3d) has been determined by means of crystal Xray diffraction methods.

La RMN a récemment prouvé son potentiel en biologie structurale. Cette thèse décrit les méthodes que nous avons développées pour l’étude de protéines par RMN du solide à haute résolution. Après une présentation des récents progrès du domaine, nous présentons les améliorations liées à l’utilisation de la rotation à l’angle magique à très haute vitesse, notamment les techniques de découplage hétéronucléaire et de polarisation croisée à basse puissance, appliquées aux cas de la Superoxide Dismutase (SOD) et de la protéine GB1. Nous détaillons ensuite les perspectives émergeant dans l’utilisation des couplages J, avec trois nouvelles séquences. La J-CHHC renseigne sur les distances entre protons, le bloc S3E améliore résolution et sensibilité en effectuant du découplage J, et l’INADEQUATE-S3E combine transfert de polarisation par couplage J et découplage J.

This thesis details metods we developed for high resolution NMR of nanocrystalline proteins. After an introductory presentation of the recent advances in solid-state NMR of bio-systems, we present the improvements we proposed in the ultra-fast magic-angle spinning regime, notably low-field heteronuclear decoupling and low-field cross-polarization. We demonstrate them with the study of the Superoxide Dismutase (SOD) and the protein GB1. We then focus on the perspectives arising for J-couplings in proteins by presenting three new sequences. The J-CHHC sequence probes 1H-1H distances encoded in 13C-13C correlation experiments. The S3E block improves resolution and sensitivity by performing J-decoupling, and the INADEQUATE-S3E combines J-based transfer of polarization and J-decoupling. We finally give perspectives to probe long-range structural constraints with data exploiting the paramagnetic properties of Cu(II)-SOD

Abstract:

This thesis concerns the NMR investigations of supramolecular metallo-nanocages as hosts for host-guest chemistry. The research is based on metallo-nanocages constructed from cyclotriveratrylene (CTV)-derivatives The host-guest interaction between the [Pd6(L1)8]⋅12(BF4) stella octangula cage and sodium alkyl sulfate guests have been characterised by 1H 1 D, DOSY and 2-D ROESY NMR and ESI-MS. The host-guest stoichiometry was determined at 1:2 by Job’s plot analysis. The shorter the length of the guest’s alkyl tail, the more tightly bound it was to the host cage. The self-assembly and self-sorting of the [Pd6(L1)8]⋅12(BF4) stella octangula cage were also investigated. d6-DMSO competed with the L1 ligand for the palladium(II) cation. The rate of self-sorting of the [Pd6(L1)8]⋅12(BF4) stella octangula cage was found to be affected by concentration, with lower concentrations resulting in cage systems that self-sorted in to homochiral cages at a faster rate. The novel FL1 ligand was characterised by 1H and 19F NMR spectroscopy in d6 DMSO and d3 MeCN and was used to produce stella octangula cage assemblies. The self-assembly of this system in d6 DMSO was observed and found to require an excess of palladium to form. This FL1 system was also investigated for host-guest interactions with sodium dodecyl sulfate (SDS). It formed a system that exhibited weaker binding than L1. The FL1 ligand formed quantitative cages in d3 MeCN. This system was characterised by 1H and 19F NMR spectroscopy, 2-D ROESY NMR, ESI-MS and X-ray crystallography. The L1 and FL1 ligands were used to form cryptophanes with [1,3 bis(diphenylphosphino)propane] in d6 DMSO, d3 MeCN and d3 MeNO2. These were characterised by 1H, 19F, 31P NMR spectroscopy, 2-D ROESY NMR, ESI-MS and X-ray crystallography. Both ligands showed a strong preference for anti cryptophane isomers in solution, although a small amount of syn isomer was observed in the L1 systems. The syn isomer was predominant species in the solid state.

Abstract:

La connaissance de la structure tridimensionnelle d’un composé solide est essentielle pour la compréhension de ses propriétés et le développement de nouveaux matériaux. La diffraction des rayons X est communément utilisée pour déterminer la structure des composés monocristallins. La caractérisation structurale de composés sous forme de poudre présente plus de difficulté. En particulier, beaucoup de composés ne peuvent pas être obtenus sous forme de monocristaux ; et les composés hautement polymorphiques (tels que la plupart des médicaments) doivent être caractérisés « tels quels » afin de limiter les risques de modification structurale. Cette thèse présente de nouvelles méthodes de cristallographie de poudre par résonance magnétique nucléaire (RMN) du solide à haute résolution, i. E. La détermination de la structure, en abondance isotopique naturelle, de composés en poudre par RMN. Dans une première partie, le cas complexe de la résolution des spectres proton est abordé. Les possibilités offertes par la dernière génération de sondes RMN sont explorées et de nouvelles méthodes de découplage sont proposées. Dans la deuxième partie, des protocoles de détermination structurale sont développés. Ces derniers s’appuient sur la forte dépendance des paramètres RMN avec les détails de la structure cristalline, et profitent de la haute résolution accessible en RMN du solide pour les protons et les carbones. Ces techniques sont appliquées à un composé test, le thymol, et démontrent le potentiel de la RMN du solide pour la résolution de la structure cristalline de composés en poudre<br>Knowledge of the three-dimensional structure is an invaluable element for the understanding of the properties of solid materials and towards the development of new materials. While single-crystal X-ray diffraction is established as the best tool to characterise monocrystalline samples, the experimental determination of the structure of polycrystalline powders remains a challenging domain. Many crystalline solids cannot be prepared as single crystals and must be characterized in the powder form. Other compounds are highly subject to polymorphism, and there is a need for structural determination techniques that minimize the risk of structural change during the characterisation. The problem is particularly relevant in the case of drug powders, which need to be accurately characterized in their active pharmaceutical form. This thesis presents new developments relating to powder nuclear magnetic resonance (NMR) crystallography, i. E. Structure determination of powdered samples using high-resolution solid-state NMR at natural isotopic abundance. The first part of the thesis concentrates on the challenging case of protons and illustrates the opportunities offered by the latest generation of commercial NMR probes and new decoupling methods. Protocols are proposed in the second part, which benefit of the high-resolution solid-state NMR spectra accessible for protons and carbons and which make use of the strong dependence of the NMR parameters on crystalline structure details. These techniques are successfully applied to a model compound, thymol, and demonstrate the potential of solid-state NMR for structural determination of powdered compounds

Abstract:

The radiofrequency (rf) pulses used in NMR are subject to a number of imperfections, such as those resulting from the inhomogeneity of the rf field or an offset of the transmitter frequency from exact resonance. In spin-echo experiments, these imperfections yield spectra with reduced signal intensity and distorted phase. Composite pulses, which have tailored bandwidth properties with respect to experimental frequency parameters such as the rf field strength or resonance offset, offer a route to improving the amplitude of the spin-echo signal. However, the symmetry of the pulse sequence must be carefully considered to prevent the introduction of phase errors into the spin-echo signal. Here, composite pulses will be studied as a means to improving one of the most common techniques for 1H background suppression in MAS NMR, the ”Depth” sequence. Novel composite 180° pulses will be presented for this application and verified experimentally. The composite pulse Depth experiment yields spectra with improved amplitude of the 1H signals of interest, while successfully maintaining good suppression of background signals. Novel families of dual-compensated 180° composite pulses for I = 1/2 will also be designed for use in NMR spin-echo experiments. These pulses are capable of simultaneously compensating for resonance offset and rf inhomogeneity problems. Crucially, unlike many composite pulses that have been presented before, these new pulses have the correct symmetry properties to form a spin echo without phase distortion. Composite pulses have found wide usage in solution-state NMR, and although in principle the same pulses can be applied in solid-state NMR experiments, complications can arise under magic angle spinning (MAS). The effects of MAS on composite pulse performance will be explored both through computer simulations and 31P experiments. Finally, on a different theme, we will investigate spin-locking of half-integer quadrupolar nuclei in solids. Spin-locking is an important feature of many NMR experiments, yet the complex behaviour observed for quadrupolar nuclei is not fully understood. Using the theoretical model introduced by Ashbrook and Wimperis, we will investigate the far off-resonance case of spinlocking for I = 3/2 and I = 5/2 nuclei.

Abstract:

The combustion performance of a wide range of fuel types has been examined utilizing a single combustor from a Rolls-Royce Tyne gas-turbine engine. The results provide further evidence to suggest that fuel total hydrogen content provides a better indication of fuel combustion perfomance than does aromatic content. However, an even better prediction of fuel combustion performance is given by smoke point, although the acknowledged imprecision of the smoke point test does militate against its use as a primary specification requirement. Analysis of certain fuels by 13C NMR and low resolution mass spectroscopy demonstrates that it is those fuels with high concentrations of polycyclic aromatics whose combustion performance in terms of flame radiation and exhaust emissions, is underpredicted by fuel total hydrogen content. There are indications that low concentrations of high molecular weight polycyclic aromatics may substantially impair combustion performance.
