ALTHOUGH much work has been carried out on the reactions of ammonia with sulphur dioxide1,2, little attention has been directed to spectrochemical measurements of the reactions. Tertiary amines (such as trimethylamine and triethylamine) and aniline derivatives give well-known molecular complexes by addition of sulphurdioxide; and ultra-violet absorption spectra3,4 for the former and infra-red absorption

characterized with matrix-isolation IR and UV–vis spectroscopy. Prolonged irradiation at 266 nm causes Curtius rearrangement of the nitrene to form N-sulfinylamine CH3NSO and S-nitrosothiol CH3SNO. By high-vacuum flashpyrolysis (HVFP) at 800 K, CH3S(O)N3 also decomposes and furnishes CH3S(O)N with minor fragmentation products HNSO and CH2 in the gas phase. A similar photo-induced Curtius-type rearrangement of
