INTENSITY IN THE RAMAN EFFECT: V. THE EFFECT OF INTERMOLECULAR INTERACTION ON THE RAMAN SPECTRUM OF CARBON DISULPHIDE

Abstract

The Raman spectrum of CS₂ has been obtained photoelectrically for the liquid and solutions of varying concentrations in cyclopentane, and depolarization ratios and intensities measured. The intensity of the forbidden bands v₂ and v₃ relative to that of the Raman active band v₁ decreases rapidly with dilution. The bands are present because of intermolecular interaction which probably occurs between the C atom of one molecule of CS₂ and only one of the S atoms of the other.
