A sing!e-crystal ESR study of copper diethyldithiophosphate has.shown hyperfme interaction with the 33S is\* tope (0.74% abundant) of the sulphur ligands, in addition to interactions with the 63\*65Cu and 31P nuclei. TWO different j3S hyperfine couplings hnve been observed and arc discussed in terms

A very weak interdimer exchange coupling was determined as a function df hydrostatic pressure up to 500 MPa from the EPR line-merging effect. The exchange integral is IJI ~0.0032 cm-t under normal conditions and increases linearly with slope d 1 JI ldp = 6 x IO -6 cm -'/MPa. Comparison between the p
