Solid-state phosphorus-31 nuclear magnetic resonance spectroscopy of phosphorus sulphides

Abstract

Magic-angle spinning ³¹P n.m.r. spectra of solid binary phosphorus sulphides P₄S_n(n= 3, 5,7, 9, or 10) have been obtained. The multiplicity of ³¹P resonances are correlated with the structural inequivalences revealed by X-ray diffraction. In the case of P₄S₅there are considerable solution-to-solid changes in the chemical shifts. Spinning side band analysis of the solid-state spectra has yielded data on effective shielding tensor components.
