In this review, an update on the structural properties and theoretical studies of N-sulfinylimine compounds (R–NySyO) is reported. They were deduced using several experimental techniques: gas–electron diffraction (GED), X-ray diffraction, 17O NMR, ultraviolet-visible absorption spectroscopy (UV–Vis), FTIR (including matrix studies of molecular randomisation) and Raman (including pre-resonant Raman spectra). Data are compared with those obtained by theoretical calculations. With these tools, excited state geometry using the time-dependent theory was calculated for these kinds of compounds. The existence of pre-resonant Raman effect was reported recently for R–NySyO compounds. The configuration of R–NySyO compounds was checked for this series confirming the existence of only one syn configuration. This finding is corroborated by theoretical calculations. The method of preparation is also summarised.N-sulfinylimine compounds (R–NySyO) is reported.
