Low-resolution low-frequency depolarized light (VH) scattering from binary mixtures of fluids and from pure fluids of nonrigid molecules

A simple formalism is presented here which describes low-resolution low-frequency depolarized light scattering from binary mixtures of fluids of nonspherical molecules and from pure fluids of nonrigid molecules, each one containing two segments. It is shown that when the k dependent features are negligible these spectra can contain two lorentzians because only dissipative modes are possible. The results presented here can also be used to describe dielectric relaxation from similar systems.
