High Resolution Far-Infrared Spectra of Thiophosgene with a Synchrotron Source: The ν2 and ν4 Bands Near 500 cm-1.

Thiophosgene (Cl2CS) is a favorite model system for studies of vibrational dynamics. But there are no previous rotationally-resolved infrared studies because the spectra are very congested due to its (relatively) large mass and multiple isotopic species. Here we report a detailed gas-phase study of the ν2 (∼504 cm-1) and ν4 (∼471 cm-1) fundamental bands, based on spectra obtained at the Canadian Light Source far-infrared beamline using synchrotron radiation and a Bruker IFS125 FT spectrometer.
