High Resolution Investigation of Some Infrared Bands of Carbon Disulfide

Abstract

Absorption bands of carbon disulfide have been measured with high resolution in the regions of 2180 and 2900 cm−1. Bands have been observed due to several isotopic species. By combining the observed bands with those previously measured, a set of harmonicity constants for 12C32S2 has been obtained in cm−1 as follows: X11, −1.070; X22, 0.126; X33, −6.54; X12, 0.860; X13, −7.86; X23, −6.45; g22, 0.656.
