摘要

Abstract: An ESR study on electron-capture phosphorus centered radicals trapped in single crystals of rac-and meso-1, 2-dimethyl-l, 2-diphenyldiphosphine disulfide (MePhP (S) P (S) MePh) is reported. The principal values and axes of the g and hyperfine coupling tensors of the radical anions are determined. It is shown that X irradiation of the two diastereoisomeric compounds results in completely different radical products. The racemate yields a radical ...
