Dielectric Properties of Low-Polarity Substances and Their Description Taking into Account Intermolecular Interactions

Optical and dielectric properties of low-polarity liquids (benzene, xylene, toluene, carbon tetrachloride, carbon disulfide) are considered. A generalized equation of dielectric polarization is suggested to describe these properties; its specific feature is the correction for the kind and intensity of intermolecular interaction. This correction is determined on the basis of the model of the molecular electronic shell expanding owing to cross self-polarization of molecules. A material equation improving the agreement of the calculated quantities with the experiment is obtained.
