Infrared Spectra of Thionyl Chloride and Sulfuryl Chloride

Abstract
The infrared spectra of thionyl chloride and sulfuryl chloride have been investigated from 400 cm—1 to to 5000 cm—1 with a prism spectrometer. Three of the fundamentals of SOCl2 have been found and four for SO2Cl2. They and the various additional bands have been assigned to their appropriate symmetry species assuming SOCl2 has C8 symmetry and SO2Cl2 has C2v symmetry.
