Features of the high-resolution IR spectra of the SiН4 molecule in low-temperature matrices of N2 and Ar at 6.6–20 K, depending on the experimental conditions, are analyzed. It was found that, in the nitrogen matrix, in the stretching region of 28

RAIR spectra of liquid and crystalline hexafluoroethane were recorded in the temperature range 100–200 K. The ν5 and ν10 reflection bands had been normalized and used to obtain their extinction profiles. New normalizing method outlined in this pa

Infrared reflection-absorption spectra of thin films of α-crystalline hexafluoroethane deposited on a gold-plated copper mirror are measured at temperatures of 70 and 80 K. The bands corresponding to strong in the dipole absorption vibrations ν5 an

Reflection-absorption IR (RAIR) spectra of sulfur hexafluoride (SF6) crystalline thin films in 10–100 K temperature range and absorption FTIR spectra of thin layer (90 μm) of liquid SF6 near the melting point (Tm = 222 K) are recorded. Special att

In the IR absorption spectra of low-temperature molecular liquids, we have observed anomalously large isotope shifts of frequencies of vibrational bands that are strong in the dipole absorption. The same effect has also been observed in their Raman s

In this paper the Raman spectrum of liquid C 2 F 6 in the spectral region 250–1500 cm −1 is presented. Data on six fundamental Raman bands of C 2 F 6 are obtained. Doublets are observed in the spectral regions of the ν 1 ( A 1 g ) (1416.3 cm −

We have studied the IR absorption spectra of diluted mixtures SiF4/M = 1/6000–1/10 000 in an N2 matrix at 11 K (for comparison, the spectra of SiF4 in Ar and Xe matrices have also been studied). It has been shown that, in solid nitrogen, the appear

To rationalize the recently found (Garbacz et al., 2012) [1] difference in magnetic shielding for H and D nuclei in HD, the contribution of excited Π g states has been considered in combination with a symmetry breaking term in Hamiltonian as perturb
