N2  - The Raman and infra-red spectra of 2-propene-1-sulphonyl chloride, 1-propene-1-sulphonyl chloride, 2-phenyl ethane and 2-phenyl ethane sulphonyl chlorides, and the infra-red spectrum of sodium 2-phenyl ethane sulphonate have been recorded. The constancy of sulphonyl, S-Cl, C-S, and C=C vibrations indicates the absence of conjugation in the ground state between C=C and S=O. The ultraviolet spectra of the styrene derivatives indicate a strong electronic interaction in the excited state. The 1-propene-1-sulphonyl chloride prepared by the method of Lambert and Rose (1949) is shown to be the trans-compound.     The constancy of the symmetric and asymmetric frequencies of the SO3 group in the ions CH3S03-, NH2SO3-, and HOS03- also shows that there is no strong inter- action between the lone pairs of electrons on the nitrogen or oxygen and the sulphur-oxygen &#960;-bond system.
