Abstract

As was demonstrated previously [1–5], the experimentally observed differences between the spectra of compounds in the vapor and condensed phases can, in some cases, be attributed to effects associated with a change in the strength of the light-wave field acting on the molecules in the condensed medium (in comparison with that in the rarified gas) rather than to intermolecular interaction resulting from the phase transition between the gas and condensed phase. The influence of the effective light-wave field on the observed absorption spectra of a number of compounds differing materially in character was illustrated earlier [3–5], using the characteristics of the C-Cl valence-vibration bands of carbon tetrachloride and chloroform. As was shown by these data [3], the spectra of condensed CCl4 and CHCl3 after introduction of a correction for the effective field were close to those of the gaseous phase in all spectroscopic parameters. As was to be expected, the best agreement was observed for the nonpolar CCl4 molecule, which corresponds more closely to the approximations used in the calculations. The spectral differences arising during the vapor-liquid phase transition for polar CHCl3 molecules are due both to the influence of the effective light-wave field and to the intermolecular interactions which are more substantial for CHCl3 than for CCl4.
