“…Using the force field from [20], we calculated the frequencies and coefficients S k of the vibration patterns of the normal modes taking into account the difference in the absorption coefficients of all the three isotopically substituted molecules. The isotope shifts ∆ν Table 3 The relative intensities ξ = A(ν k )/A(ν 1 + ν 3 ) presented in Table 1 are obtained by averaging of the measurements in solutions in liquefied Ar at 90 K and in Kr at 160-170 K. The measurement errors of the relative intensities of the bands of the same order are within 2-5%.…”

-The spectral characteristics of the SiF 4 molecule in the range 3100-700 cm -1 , including the absorption range of the band ν 3 , are studied in the gas phase at P = 0.4-7 bar and in solutions in liquefied Ar and Kr. In the cryogenic solutions, the relative intensities of the vibrational bands, including the bands of the isotopically substituted molecules, are determined. The absorption coefficients of the combination bands 2 ν 3 , ν 3 + ν 1 , ν 3 + ν 4 , and 3 ν 4 are measured in the solution in Kr. In the gas phase of the one-component system at an elevated pressure of SiF 4 , the integrated absorption coefficient of the absorption band ν 3 of the 28 SiF 4 molecule was measured to be A ( ν 3 ) = 700 ± 30 km/mol. Within the limits of experimental error, this absorption coefficient is consistent with estimates obtained from independent measurements and virtually coincides with the coefficient A ( ν 3 ) = 691 km/mol calculated in this study by the quantum-chemical method MP2(full) with the basis set cc -p VQZ .

“…In assigning absorption bands and lines of impurities in the gas phase, we used earlier data for SiF 4 and SiH 4 [10,11], HITRAN Database resources [12] (HF, H 2 O, CO, CO 2 , and CH 4 molecules), and earlier data for hexafluorodisiloxane, trifluorohydroxysilane, and fluorosilanes [13][14][15][16][17][18][19][20][21].…”

-The impurity compositions of silicon tetrafluoride and silane prepared from it have been determined by high-resolution Fourier-transform IR spectroscopy. In the spectra of SiF 4 samples differing in purity, we have identified rovibrational bands arising from Si 2 F 6 O, SiF 3 OH, HF, SiF 3 H, SiF 2 H 2 , SiH 3 F, CH 4 , CO 2 , and CO impurities. Their detection limits lie in the range 9 × 10 -5 (CO 2 ) to 3 × 10 -3 mol % (Si 2 F 6 O). In the spectra of SiH 4 samples of different purity, we have detected CH 4 , CO 2 , SiF 3 H, SiF 2 H 2 , and SiF 4 impurities. Their detection limits lie in the range 8 × 10 -5 (CO 2 ) to 1 × 10 -3 mol % (SiF 4 ).
