Abstract:
A review of the development of the Wolkenstein valence-optical (VO) theory of the integral characteristics of Raman spectra is given. Invariant expressions for the anisotropy of the molecular polarizability tensor and the anisotropy of the derived (in normal coordinates) polarizability tensor, which are independent of the choice of the coordinate system fixed in the molecule, are obtained. The most recent data for Raman intensities of methane and carbon tetrachloride are used and the electrooptical parameters of the C-H and C-Cl bonds are calculated. The consistency of the zeroth-order approximation of the VO theory is shown for the considered molecules. A critical analysis of attempts to introduce the first-order approximation into the VO theory is carried out.
