Abstract
The infrared spectra of 1,2,5-thiadiazole and 1,2,5-thiadiazole-d2 in the gaseous and liquid states, have been measured between 4000 and 400 cm−1. The Raman spectrum of liquid 1,2,5-thiadiazole has also been obtained. An assignment of all the infrared active modes was based on the rotational envelope contours of the gas phase spectra, the isotope shift and the polarization measurements of the Raman spectrum. The two infrared inactive but Raman active A2 modes were not detected.
