Abstract
The infrared and Raman spectra of H2S3 and H2S4 in CCl4 and CS2 solutions are reported and a complete assignment is presented. On the basis of the spectra and their temperature and concentration dependence, H2S3 is considered to be in the GG and H2S4 in the GG′G conformation. A valence force field is derived which provides a least-squares fit between observed and calculated frequencies for both molecules simultaneously, with an average error of 1.5 cm−1 (or 0.4%) over all frequencies.Keywords
