Abstract
An empirical relationship between ΔJgem and a relative orientation of a methylene group attached to oxygen and sulphur, and two groups, sulphonyl and sulphinyl, has been experimentally determined. The empirical curve for oxygen shows marked similarity to a theoretically derived curve relating the magnitude of Jgem in the rotamers of methanol about the C–O bond. All four curves bear out the predictions of the theory of geminal coupling.
