The rotation about the sulphur(IV)–nitrogen bond in SS-dimethyl-N-methylsulphonylsulphilimine (Me2S:N·SO2Me) has been investigated theoretically by the extended Huckel Method; the symmetry properties of the molecule, the anomalies in its n.m.r. spectrum, and the fact that S-symmetrical sulphilimines cannot be resolved into antipodes are explained on the basis of the shape of the total energy curve.
