The Raman spectra of liquid and gaseous sulfuryl fluoride (SO2F2) and of liquid thionyl fluoride (SOF2) have been investigated and depolization factors measured for the stronger lines scattered by the liquids. For SO2F2 the Raman shift due to the infrared inactive torsional mode has been found to be 388 cm—1, and other previous assignments based on the infrared spectrum have been confirmed. For SOF2, the symmetric SF2 stretch occurs at a higher frequency than the asymmetric stretch; the reverse is true for SO2F2. The symmetric SF2 bending mode has escaped detection for both compounds.
