Discrepant interpretations regarding the frequency of the C=S stretching mode are reviewed and assignments of frequencies for the vibrational modes of the xanthate group, [Formula: see text] are presented.A band at 1020–1070 cm −1 is assigned to the C=S stretching mode. Bands at 1200 cm −1 and 1110–1140 cm −1 are ascribed to the stretching vibrations of the C—O—C linkage.The effects of the alkyl hydrocarbon chain length and of metal atoms (alkali metals, copper, and zinc) in displacing some of the frequencies are recorded.
