Infrared and Raman Spectra of Carbon Subsulfide

Abstract
Infrared and Raman spectra of carbon subsulfide (C3S2) in various phases have been obtained in the region 30–4000 cm−1. Mass and ultraviolet spectra are also presented. Analysis of the vibrational spectra indicates a Dh structure. Of particular interest is the 94‐cm−1 band assigned as ν7, the central‐carbon bending frequency, which lies at a higher frequency than the analogous band in C3O2. A vibrational analysis has also been performed.
