Moment analysis in depolarized light scattering: determination of a single-parameter empirical pair-polarizability anisotropy for mercury

摘要

A method based on classical physics, utilizing the first two even moments of the depolarized collision-induced light-scattering spectrum at various temperatures to derive an empirical model for the pair-polarizability anisotropy of interacting molecules, with only one adjustable parameter, is described and applied to the spectra of Hg. Good agreement with ab initio results in the literature is obtained and profiles calculated with these models are in excellent agreement with experiment.
