Observation of Hot Bands in the Raman Spectra of Cl2 Gas and CCl4 Vapor

Abstract
Hot bands were resolved in the vibrational Raman spectrum of chlorine at atmospheric pressure. The anharmonicity constant is in good agreement with the value obtained from absorption spectra. In carbon tetrachloride vapor the hot bands contributing the the ν1 band contour were investigated from 25° to 130°C.
