A theory for the intermolecular nucleus-electron scalar interaction and its application to dynamic polarisation results of phosphorus-31 nuclei

Abstract

A perturbation theory which allows the size of the intermolecular nucleus-electron scalar interaction to be estimated, is presented. Measurements of the dynamic polarisation of ³¹P nuclei in a variety of systems in solutions containing the tri-t-butylphenoxyl radical are reported; the results are interpreted qualitatively in terms of the theory. ³¹P Chemical shifts and coupling constants have been measured for a number of the compounds.
