Comparison of interaction induced light scattering and infrared absorption in liquids

Abstract

The spectra of scattered depolarised light and infrared (IR) absorption in Ne, Ar, Kr, Xe, CH₄ and CF₄ are investigated. The spectra were analysed in terms of a two component induction mechanism for the light scattering—a long range DID and a short range mechanism—and a single short range interaction for the IR.

It is concluded that at liquid densities the high frequency portions of both spectra arise from isolated binary collisions at liquid densities. It is argued that the short range interaction mechanisms in the molecular and atomic liquids are the same if one considers interactions as occurring between the individual atoms of neighbouring molecules.
