Sulphur-33 nuclear magnetic resonance studies of sulphur compounds with sharp resonance lines. 33S NMR spectra of some sulphones and sulphonic acids

³³S NMR spectra have been obtained in the FT mode for some sulphones and sulphonic acids. The investigated compounds show narrow resonance lines. In the case of sulphones, the range of ³³S chemical shifts is sufficiently wide, i.e. the effects due to changes in substituents are significant enough to allow further use of the ³³S NMR of sulphones for quantitative analysis in petroleum chemistry.
