Multidimensional ultrafast spectroscopies are one of the premier tools to investigate condensed phase dynamics of biological, chemical and functional nanomaterial systems. As they reach maturity, the variety of frequency domains that can be explored has vastly increased, with experimental techniques capable of correlating excitation and emission frequencies from the terahertz through to the ultraviolet. Some of the most recent innovations also include extreme cross-peak spectroscopies that directly correlate the dynamics of electronic and vibrational states. This review article summarizes the key technological advances that have permitted these recent advances, and the insights gained from new multidimensional spectroscopic probes.

AbstractA novel Schiff base was synthesized and characterized by spectroscopic and theoretical methods. A potentially active agent 4-(2-hydroxy-5-methylphenylimino)naphthalen-1(4H)-one (PINQ) was designed and synthesized. The synthesis was carried out by a condensation reaction of 1-4-naphthoquinone and 2-amino-4-methyl phenol. The spectral and structural properties of the PINQ molecule were investigated by elemental analysis, 1H- and 13C-NMR, FT-IR and Uv-vis spectroscopies. The energetic, atomic, electronic, molecular, vibrational and magnetic data were theoretically obtained using density functional theory (DFT) at B3LYP level with 6-311++G(d,p) basis set. Chemical shifts were calculated using gauge-invariant atomic orbital (GIAO) method. UV-vis spectrum for the title compound was also obtained by time-dependent density functional theory (TD-DFT). The theoretical and experimental results were compared and interpreted. The theoretical data obtained from 1H- and 13C-NMR, FT-IR and Uv-vis spectroscopies were quite compatible with experimental ones.

This paper discusses the applicability of optical and vibrational spectroscopies for the identification and characterization of the T-2 mycotoxin. Vibrational states and electronic structure of the T-2 toxin molecules are simulated using a density-functional quantum-mechanical approach. A numerical experiment aimed at comparing the predicted structural, vibrational and electronic properties of the T-2 toxin with analogous characteristics of the structurally similar 3-deacetylcalonectrin is performed, and the characteristic spectral features that can be used as fingerprints of the T-2 toxin are determined. It is shown that theoretical studies of the structure and spectroscopic features of trichothecene molecules facilitate the development of methods for the detection and characterization of the metabolites.

Ultrafast structural dynamics is an emerging field aiming to deliver a detailed understanding of the elementary steps in reacting chemical species, which involve changes in their nuclear, electronic and spin states. Such processes are vital ingredients in chemistry and biology, but also in technological applications, including efficient charge transport in solar energy converters and ultrafast switchable molecular magnets. In order to unravel the complex dynamic behavior in photoexcited molecules we have implemented a suite of ultrafast x-ray spectroscopic and scattering tools to zoom into both the electronic and nuclear structures, with the goal to ultimately deliver a molecular movie of ongoing chemical processes. In view of the many potential applications in chemical and biological dynamics it is desirable to increase the signal-to-noise (S/N) level of such experiments as well as to decrease the time resolution into the femtosecond time domain. We present our benchmark results using a versatile setup that permits simultaneous measurements of ultrafast x-ray absorption and emission spectroscopies combined with x-ray diffuse scattering. This combined scattering and spectroscopic approach has recently been established by us at different synchrotron [1-2] and XFEL [3] lightsources. We applied it to study different photochemical systems in liquid media, ranging from nascent radicals in solution to photocatalytic systems, with the goal to deliver a deeper understanding of the elementary steps in chemical reactivity.

The enhanced luminescence of lanthanide complexes coordinated to antenna ligands has potential applications for developing devices like screens and lamps. Herein, three β-diketone antenna ligands were incorporated into Eu(III) and Tb(III) metals to synthesize five complexes. Their luminescence properties in solid state and the energy levels of the electronic states for the ligands and the metals were recorded and probed by UV–vis and fluorescence spectroscopies. Under UV light, a white-light emission powder was observed by mixing red-emission europium and green-emission terbium complexes, with blue-emission laundry powder. The powder composition was tuned by using spectroscopic analysis and CIE 1931 color diagram.

Water is an ubiquitous liquid that has several exotic and anomalous properties. Despite its apparent simple chemical formula, its capability of forming a dynamic network of hydrogen bonds leads to a rich variety of physics. Here we study the vibrations of water using molecular dynamics simulations, mainly concentrating on the Raman and infrared spectroscopic signatures. We investigate the consequences of the temperature on the vibrational frequencies, and we enter the details of the hydrogen bonding coordination by using restrained simulations in order to gain quantitative insight on the dependence of the frequencies on the neighbouring molecules. Further we consider the differences due to the different methods of solving the electronic structure to evaluate the forces on the ions, and report results on the angular correlations, isotopic mixtures HOD in H2O/D2O and and the dielectric constants in water.

The valence-band and conduction-band electronic structure of pyrite-type CoSe 2 has been investigated by means of ultraviolet-photoemission, synchrotron-radiation-photoemission and inverse-photoemission spectroscopies. The fully occupied Co 3d states with t 2g symmetry are observed as a main peak at -1.0 eV relative to the Fermi level (E F ), and the partially filled Co 3d states with e g symmetry are observed as a shoulder at the E F side of the main peak. On the other hand, the structure due to the unoccupied Co e g states appears at 0.6 eV in the inverse-photoemission spectrum. The electronic structure of CoSe 2 is similar to that of CoS 2. The electron correlation is more important for CoSe 2 than for CoS 2.

Novel Schiff base 2-((E)-(1H-indol-5-ylimino)methyl)-4-nitrophenol ligand and its Mn(II), Co(II), Ni(II), Cu(II), Zn(II) and Pd(II) complexes were synthesized by the stoichiometric reactions between the metal (II) ions and ligand in molar ratio M:L (1:1). The synthesized compounds were characterized using melting point, solubility, molar conductance, room temperature magnetic susceptibility, infra-red and electronic spectroscopies. The assignments of four-coordinate tetrahedral/square planar geometries and the bidentate nature to the complexes was corroborated by IR, electronic spectroscopies, and magnetic moments. The Pd(II) complex however was assigned an octahedral geometry. The in-vitro antimicrobial studies revealed the potential of some of the compounds as antimicrobial agents. The ligand and its metal complexes exhibited good to moderate antimicrobial activity against tested bacteria with selective inactivity against P. mirabilis and P. aureginosa. Keywords: 2-((E)-(1H-indol-5-ylimino)methyl)-4-nitrophenol, magnetic susceptibility, square planar geometry, inhibitory zone.

Annotation:

Possible ferro-electromagnetic performance of “ reduced graphene oxide ( r-GO)” deposited on the surface of “ ZnO-nanorod ( NR) decorated with nanocrystalline ( nc) Au particles” is studied using different spectroscopies and magnetic measurements. The presence of carbon/zinc-interstitials (Zn i), nc-Au, and oxygen vacancies are established through electronic property studies using different spectroscopic measurements. The magnetic moment (M) applied magnetic field (H) curve and electrical measurement current (I)–voltage (V) loops show that nc-Au/ZnO-NRs:r-GO is ferromagnetic and partial ferroelectric, respectively. The work functions are obtained from the lower kinetic energy of ultraviolet photoelectron spectroscopy, which is correlated with the enhancement of ferro-electro-magnetic performance. Both ferroelectric and ferromagnetic performance of nc-Au/ZnO-NRs:r-GO nanocomposite material could be useful for ferro-electro-magnetic technological applications.

High-valent iron species are key intermediates in oxidative biological processes, but hexavalent complexes apart from the ferrate ion are exceedingly rare. Here, we report the synthesis and structural and spectroscopic characterization of a stable Fe(VI) complex (3) prepared by facile one-electron oxidation of an Fe(V) bis(imido) (2). Single-crystal x-ray diffraction of 2 and 3 revealed four-coordinate Fe centers with an unusual “seesaw” geometry. 57Fe Mössbauer, x-ray photoelectron, x-ray absorption, and electron-nuclear double resonance (ENDOR) spectroscopies, supported by electronic structure calculations, support a low-spin (S = 1/2) d3 Fe(V) configuration in 2 and a diamagnetic (S = 0) d2 Fe(VI) configuration in 3. Their shared seesaw geometry is electronically dictated by a balance of Fe-imido σ- and π-bonding interactions.

High-resolution hard x-ray spectroscopies (XES, HERFD, RIXS, XRS) are now well-established characterization tools for providing insights of material's electronic and geometric structure. The high brilliance synchrotron radiation beamlines have made feasible the routine study of the electronic structure and ligand environment of metal coordination compounds and active centers in metalloproteins, electrochemical process under in-situ conditions, as well as studies on catalytic systems under ambient conditions. Moreover, the recent availability of Linac Coherent Light Source (LCLS), provides some unique opportunities for the study of ultrafast electronic structure dynamics in various phenomena such as electron transfer processes, transient molecular states, molecular dissociation, etc. At SLAC National Accelerator Laboratory we have developed recently a set of high-resolution x-ray spectroscopic capabilities based on various multicrystal spectrometers. At SSRL we have built three multicrystal Johann spectrometers enabling XES/RIXS/HERDF techniques as well as X-ray Raman Spectroscopy. For LCLS, we have developed an energy dispersive multicrystal von Hamos spectrometer that records simultaneously the overall emission spectrum, enabling shot-by-shot time-resolved studies. Representative examples of application will be shown and discussed from the ongoing spectroscopy programs of SSRL and LCLS.

Annotation:

Reduction-oxidation (redox) reactions that transfer conduction electrons from the anode to the cathode are the fundamental processes responsible for generating power in Li-ion batteries. Electronic and microstructural features of the cathode material are controlled by the nature of the redox orbitals and how they respond to Li intercalation. Thus, redox orbitals play a key role in performance of the battery and its degradation with cycling. We unravel spectroscopic descriptors that can be used to gain an atomic-scale handle on the redox mechanisms underlying Li-ion batteries. Our focus is on X-ray Compton Scattering and Positron Annihilation spectroscopies and the related computational approaches for the purpose of identifying orbitals involved in electrochemical transformations in the cathode. This review provides insight into the workings of lithium-ion batteries and opens a pathway for rational design of next-generation battery materials.
