β¦ Synopsis
A hi&resolution 31P NMR spectrum has been recorded in polycrystalline tetraphosphoros trisulphide PqSa_ The spectrum exhibits the resolved doublet and quartet structure characteristic of an AB3 type spectrum, with chemical shift difference 185 f 2 ppm and J = 70 + 3 Hz.

A simple phase alternated multiple pulse sequence is described which enables the chemicai shift between two inequivalent sites in a solid to be resolved. Preliminary experiments on solid zinc phosphide give a shift between the two inequivalent sites of 34 ppm. which could include a mean anisotropic
