Résumé :
FT-IR photoacoustic (PA) and also photothermal beam deflection (PBD) spectra were recorded with the same particulate samples (graphite, charcoal, aspirin, and silica) under the same conditions in order to compare the quality of the spectra obtainable with the two techniques. A PA cell fitted with windows for the PBD laser probe beam was used, and PA and PBD spectra of each sample were recorded at 8 cm−1 resolution at each of the four different interferometer scan velocities. Although the overall aspects of FT-IR/PA and FT-IR/PBD spectra are the same, the signal-to-noise ratios of PA spectra are appreciably better than those of PBD spectra because PBD detection is more prone to disturbance by vibration than is PA detection. Absorption bands appear at the same wavenumbers in PA and PBD spectra. However, the relative intensities of bands of PBD spectra depend on the absorptive properties of the powdered solids; with weak absorbers, some bands may not be detected at all. PAS can be used with all powders. PBDS is of little or no use for the examination of weakly absorbing powders unless they scatter IR radiation extensively.

Résumé :
Dynamic two-dimensional infrared (2D IR) correlation maps are a convenient means of examining the information contained in time-resolved IR spectra. Dynamic 2D IR spectra can be collected with the use of either dispersive or Fourier transform (FT) IR spectrometers. Use of a step-scanning FT-IR spectrometer has advantages over conventional rapid-scan FT-IR spectrometry when one is acquiring time-resolved IR data on time scales faster than about 0.1 s, because the spectral multiplexing is removed from the time domain. Dynamic IR spectra of atactic polystyrene (undergoing a small-amplitude oscillatory strain) collected on both dispersive and FT instrumentation are compared. Although the dispersive approach produces higher signal-to-noise ratios over small spectral regions, the multiplex advantage makes the FT approach attractive when broader spectral coverages are required. The first vibrational circular dichroism (VCD) spectrum [of (–)- α;-pinene] collected on a step-scanning interferometer is also presented.

Résumé :
Abstract Background: Fourier-transform infrared (FT-IR) spectrometry has been used to measure small molecules in plasma. We wished to extend this use to measurement of plasma proteins. Methods: We analyzed plasma proteins, glucose, lactate, and urea in 49 blood samples from 35 healthy subjects and 14 patients. For determining the concentration of each biomolecule, the method used the following steps: (a) The biomolecule was sought for which the correlation between spectral range areas of plasma FT-IR spectra and concentrations determined by comparison method was greatest. (b) The IR absorption of the biomolecule at the most characteristic spectral range was calculated by analyzing pure samples of known concentrations. (c) The plasma concentration of the biomolecule was determined using the FT-IR absorption of the pure compound and the integration value obtained for the plasma FT-IR spectra. (d) The spectral contribution of the biomolecule was subtracted from the plasma FT-IR spectra, and the resulting spectra were saved for further analyses. (e) The same method was then applied to determining the concentrations of other biomolecules by sequentially comparing the resulting FT-IR spectra. Results: Results agreed with those obtained by clinical methods for the following biomolecules when analyzed in the following order: albumin, glucose, fibrinogen, IgG2, lactate, IgG1, α1-antitrypsin, α2-macroglobulin, transferrin, apolipoprotein (Apo)-A1, urea, Apo-B, IgM, Apo-C3, IgA, IgG4, IgG3, IgD, haptoglobin, and α1-acid glycoprotein. Conclusion: FT-IR spectrometry is a useful tool for determining concentrations of several plasma biomolecules.

Résumé :
FT-IR spectra were recorded of <i>Escherichia coli</i> cell mass with the aim of obtaining spectral traits possibly useful in a rapid detection and characterisation of this indicator bacterium. A well differentiated spectrum was obtained from the cell mass harvested in a stationary phase of growth, e.g., after 24 h, from a minimum nutrient broth. The cell mass, harvested either earlier or grown in nutrient solutions which contained an enhanced carbon or nitrogen concentrations delivered somewhat different IR spectra, apparently due to a higher content of nucleic acid components as related to other structural constituents of bacterial cells. Consequently, the FT-IR spectra of <i>E. coli</i>, although rather rapidly to collect, seem only capable of delivering useful and reproducible information if the cell mass is obtained under standardised cultural conditions.

Résumé :
A combination of Fourier transform infrared (FT-IR) spectroscopy and microscopy, FT-IR microspectroscopy, has been used to characterize sections of human colorectal adenocarcinoma. In this report, a database of 2601 high quality FT-IR point spectra from 26 patient samples and seven different histological structures was recorded and analyzed. The computer-based analysis of the IR spectra was carried out in four steps: (1) an initial test for spectral quality, (2) data pre-processing, (3) data reduction and feature selection, and (4) classification of the tissue spectra by multivariate pattern recognition techniques such as hierarchical clustering and artificial neural network analysis. Furthermore, an example of how spectral databases can be utilized to reassemble false color images of tissue samples is presented. The overall classification accuracy attained by optimized artificial neural networks reached 95%, highlighting the great potential of FT-IR microspectroscopy as a potentially valuable, reagent-free technique for the characterization of tissue specimens. However, technical improvements and the compilation of validated spectral databases are essential prerequisites to make the infrared technique applicable to routine and experimental clinical analysis.

Résumé :
Comparisons of spectra from direct-deposition (DD) capillary gas chromatography (GC) and supercritical fluid chromatography (SFC)/Fourier transform infrared (FT-IR) measurements of two quinones with C2 symmetry axes and several barbiturates to spectra from condensed-phase libraries of the corresponding compounds are reported. The best spectral search results were obtained when the eluites were deposited on an amorphous substrate, such as ZnSe. A small number of polar, hydrogen-bonding compounds were found to align with each other or with a crystalline substrate. Different crystalline forms of some polymorphic analytes can also yield ambiguous identifications. These effects produce enough differences in the DD GC/FT-IR and SFC/FT-IR spectra to cause occasional incorrect identifications when the spectra are searched against KBr-disk library spectra.

Résumé :
In this thesis, I have discussed the feasibility to use the Fourier Transform Infrared techniques (FT-IR) as supporting tool during the pre-treatment phases of restored samples for radiocarbon dating by Accelerator Mass Spectrometry (AMS). The pre-treatment is a crucial step for the removal of possible contaminations due to exogenous carbon present in the material that causes an alteration of original 14C concentration. In particular, if the contaminations are due to material rich in fossil carbon, they produce an apparent aging of the dated sample. The fossil contamination can be due to the typical synthetic product used to restore materials in the Cultural Heritage field since the 1960s. One of the most widespread products is the acrylic resin Paraloid B72. The removal of this substance is generally complicated by the fact that the resin, subjected to the photochemical action and time aging effects, undergoes transformations in the molecular structure that cause a remarkable decrease of solubility in common organic solvents. My PhD activity has especially focused to all the phases involving the preparation and the pre-treatment of samples to be dated. The mechanical cleaning and the simple pretreatment Acid-Base-Acid (ABA), usually applied to clean the samples from naturally occurring pollutants, are not sufficient to eliminate this kind of contamination. A procedure based on chloroform (CHCl3) as the key solvent is proposed. The effectiveness of chloroform as a solvent for the removal of Paraloid B72 was the first step to be checked. The second step was test the Fourier Transform Infrared Spectroscopy (FT-IR) technique as a supporting tool to answer to basic questions: whether estimate if Paraloid B72 is present on the sample to be dated is possible and whether we can discriminate if our sample pre-treatment has been successful in the removal the possible contaminants. FT-IR has been chosen thanks to its great sensitivity to detect the functional groups of organic molecules. In addition, FT-IR technique requires small samples to acquire a spectrum. This is indispensable key points when dealing with samples in the field of Cultural Heritage. The samples principally investigates were wood and bone samples. These materials were chosen because they represent very usual samples in radiocarbon dating. Wood is one of the most common materials in the Cultural Heritage field and bones are the typical findings in an archaeological context. The problem of interfering bands, added to the great difficulty to prepare homogenous KBr pellets when dealing those samples, has headed the use of FT-IR as monitoring tool of liquid extracts, performed during the chloroform-based procedure. Definitely, the FT-IR technique is proved to be a great helpful tool in the case of spectra acquired on extracts, since it can verify whether the sample pretreatment has been successful or not. This allows us to decide how many extractions are needed during the pre-treatment process. Considering this powerful aspect, the use of FT-IT could be regularly introduced to monitor sample preparation for those restored sample to be radiocarbon dated.

Résumé :
Stone artworks and easel paintings are challenged by diverse degradations. In particularly, this thesis focuses on two restoration issues mainly induced by liquid water or moisture, which are stone degradation and blanching of easel paintings. From previous research, partially perfluorinated derivatives have been proved to provide promising restoration performance on those two restoration issues, by showing good water repellency as stone protective products and decreasing blanching in easel paintings. Inspired by those results, two families of partially perfluorinated derivatives with hydroxyl groups are proposed and designed as stone protection and blanching painting restoration products in this thesis. Those hydroxyl groups could give good adhesion on polar stone substrates by hydrogen bonding. Meanwhile, hydrophobicity of the compounds can be realized by the perfluorinated chains. The first compounds proposed and synthesized are partially perfluorinated C-glycosides. C-glycosides are carbon-linked analogues of naturally occurring sugars, which have high hydrophilic properties due to the polar hydroxyl groups. In addition to the hydrophilicity and water repellency, C-glycosides themselves possess an improved stability towards hydrolysis. Starting from the unprotected carbohydrate, the natural, renewable and cheap D-glucose, via Lubineau reaction and followed by the convenient one-pot reductive amination reaction, the target compound (partially perfluorinated C-glycoside) was successfully obtained. Moreover, partially perfluorinated C-glycoside with acetyl groups as protecting groups has been successfully synthesized as a control compound, in order to investigate if hydroxyl groups in C-glycoside can improve the restoration efficacy as expected. Then, those new partially perfluorinated C-glycosides have been tested on stone materials as protective products, and on blanching mock-up painting samples. The results indicated that different properties of those C-glycosides caused by the hydroxyls, like physical states, solubility, color and interaction with stone and painting substrates, have been influenced their behaviors as the restoration products. The other series of compounds proposed is partially perfluorinated hydroxylated oligoamides. In order to further improve the interaction between partially perfluorinated oligomers and polar substrates, new partially perfluorinated hydroxylated oligoamides derived from different monomers (dimethyl L-tartrate, diethyl succinate, diethylenetriamine or ethylenediamine) have been successfully synthesized. Those compounds have different structures and properties, i.e. solubility, hydrophilicity, chain length, molecular weight, and etc. Moreover, in order to understand the roles of hydroxyl group and amine in the applicative performance, new partially perfluorinated oligamides with no hydroxyl groups, but with the unchanged amine and succinate sources were successfully synthesized. Then, those new partially perfluorinated derivatives were tested on stone and mock-up blanching painting samples. The results showed that their efficacy for restoration was highly influenced by the structures and properties of the molecules. At the end, 4 promising new partially perfluorinated derivatives for stone protection and blanching painting restoration have been selected. Further optimization of the structures of molecules and their practical process for the application on stone artefacts and easel paintings worth being developed in the future to go deeper on this main cultural heritage approach.
