• Spectra of depolarized Rayleigh wings were observed for the liquids and CCl<SUB>4</SUB> solutions of C<SUB>6</SUB>H<SUB>6</SUB>, CH<SUB>3</SUB>CN, and CHCl<SUB>3</SUB>. The spectral band shape can be reproduced very well by a Lorentz function for the low frequency wing component and a Gauss function for the far wing component. The functions for neat liquids gave the relaxation times for orientational motion, which support free rotation models. The relaxation times of the solutions were found to be independent of concentration, the integrated intensities showing a linear dependence on concentration. The results for the wing component are in marked contrast to those found for the central component of the spectra. The difference is discussed in terms of dynamical structure of the liquids.
