The nanoporous material mayenite was synthesized by two methods: solid-phase and self-propagating high-temperature (combusting) (SHS) syntheses. The structure of the materials was determined by the X-ray diffraction analysis and IR and Raman spectroscopy.

We have measured and interpreted the IR spectra of liquid ozone films at 78–85 K and ozone dissolved in liquid argon at 91–95 K. A less hindered rotation of ozone molecules in argon manifests itself as an intensity redistribution, caused by the Coriolis interaction, from the states ν3(B1) and ν1 + ν3(B1) to the states ν1(A1) and 2ν1(A1), respectively. The occurrence of wings in the contours of the bands ν1(A1), 2ν1(A1), and 2ν3(A1) in liquid Ar and their absence in the spectrum of O3 also confirms the conclusion that the rotational motion of ozone molecules in an inert solvent at low temperatures is relatively less hindered. Maxima of ozone bands in Ar solution are shifted toward lower frequencies compared to those in the gas phase by 1–30 cm−1, which corresponds to the following shifts of harmonic frequencies of the molecule: Δω1 = −1.85(5) cm−1, Δω2 = −0.67(7) cm−1, Δω3=−7.20(5) cm−1. It was found that the absorption band of the ν3 mode in the spectrum of O3 in the liquid phase has a complicated asymmetric contour because of the resonance dipole-dipole interaction. The first and second spectral moments of this band have been determined to be M1 = 1030.6 cm−1 and M2 = 240.0 cm−2.

The three-dimensional vibrational problem for the isolated van der Waals complex formed by the Li+ cation with the N2 molecule is solved by the variational method. The potential energy and dipole moment surfaces are calculated using different basis sets of atomic functions and different approaches for taking electron correlation into account. The anharmonic effects caused by the interaction of vibrational degrees of freedom of the complex are consistently considered for the first time. The energy levels of three-dimensional vibrational states are determined. The frequency shift of the N2 molecule vibration upon complexation and the fundamental transition intensity for this vibration in the complex are calculated. The frequencies and intensities for a number of spectral transitions between the states associated with excitation of low-frequency modes are determined. The average values of geometrical parameters and their variances are calculated for the ground state and excited vibrational states of the complex.

Zeolite Na-ETS-10 is studied by the Raman and IR spectroscopy methods. The ethylene polymerization reaction on this zeolite under UV irradiation is studied by IR spectroscopy. It is found that this reaction proceeds at room temperature yielding polyethylene. The experimental data are analyzed using 2D correlation spectroscopy.

We have measured and interpreted the IR spectra of ozone dissolved in liquid nitrogen, oxygen, argon, and krypton in the 650-4700cm-1 spectral region at 79-117K. Frequency shifts, band intensities and bandshapes of 22 spectral features of soluted ozone were analyzed. The bands of the А1 symmetry have a complex contour and possess an excess intensity with respect to the value of the purely vibrational transition moment. It was found that this effect is related to the manifestation of the Coriolis interaction. The bandshape distortion manifests itself as an additional intensity from the side of the В1 symmetry band being an intensity source in the case of the Coriolis interaction.

The equilibrium nuclear configuration and the potential energy and dipole moment component surfaces of an isolated Li+–CO complex are calculated quantum-mechanically in the MP4(SDQ)/6-311++G(3df) approximation. The geometrical parameters and the binding energy of the complex are determined. The frequencies and intensities for the fundamental transitions are calculated in the harmonic approximation. The one-, two-, and three-dimensional anharmonic vibrational Schrödinger equations are solved using the variational method. The energies of states of a three-dimensional vibrational system, anharmonic constants, and the frequencies and intensities of fundamental transitions are determined with the anharmonic interactions taken into account. The changes in the frequency and intensity of the C–O stretching vibration upon the formation of the complex are predicted.
