Abstract

Abstract The infrared spectra between 4000-400 cm −1 of benzenesulphonamide, benzenesulphonanilide, benzenesulphonyl chloride and diphenyl sulphone are reported together with the spectra of the corresponding pentadeuterobenzenesulphonyl compounds. The isotopic shift of the characteristic bands near 1090 cm −1 of benzenesulphonyl compounds gives an evidence of the assignment of this band to a mixed mode of the CS stretching and a ring skeletal vibration. It is shown that the benzene and deuterobenzene ring frequencies of these compounds are in close correspondence with those of chlorobenzene and chlorobenzene- d 5. The effects of the N-deuteration and the ring deuteration on the SO 2 group frequencies are discussed.
