Abstract
Analysis of the central component of the depolarized Rayleigh light scattering spectrum of nitrobenzene is complex. Existing experimental data for nitrobenzene, including the concentration and temperature dependence of the Rayleigh linewidth, the concentration dependence of the depolarized Rayleigh intensity, and the translational-rotational coupling parameter, are analyzed using asymmetric top equations to obtain the orientational pair correlation parameters. The results of this analysis and the translational-rotational coupling parameter are used to explain the temperature dependence of the δ parameter introduced by Lempert and Wang [J. Chem. Phys. 72, 3490 (1980)]. Finally, an equation for the depolarized Rayleigh doublet for a liquid composed of asymmetric top molecules (nitrobenzene) is presented. This result is similar to previous results for liquids composed of symmetric top molecules.
