Abstract

A quantitative interpretation of the 13C/12C vapor pressure isotope effect (VPIE) in CS2 indicates that the frequency shift on condensation in the asymmetric stretching mode, υ3, to be ascribed to the effect of intermolecular forces is 13 ±3 cm-1. When combined with the spectroscopically observed shift, 27cm-1, a soundly based value for the "dielectric correction" for this absorption band is obtained. The result is of interest, and indicates that thermodynamic data on isotope effects can be used to test this aspect of spectroscopic theory.
