| Abstract | Thiophosgene (Cl2CS) is a favorite model system for studies of photophysics, vibrational dynamics, and intersystem interaction effects. But there are no previous rotationally-resolved infrared studies because the spectra are very congested due to hot bands and multiple isotopic species. This paper reports a detailed study of the ν2 (not, vert, similar504 cm−1) and ν4 (not, vert, similar471 cm−1) fundamental bands for the two most abundant isotopomers, 35Cl2CS and 35Cl37ClCS, based on spectra with observed line widths of not, vert, similar0.0008 cm−1 obtained at the Canadian Light Source far-infrared beamline using synchrotron radiation and a Bruker IFS125 Fourier transform spectrometer. |
