Abstract

Phosphorus-31 spin-lattice relaxation times and ³¹P-{¹H} nuclear Overhauser enhancements are reported for three diphosphines and eight diphosphine disulphides. In three instances work was carried out at several temperature, The (³¹P, ¹H) dipolar contributions to relaxation vary with substituent bulk and temperature, particularly for the diphosphines. It is probable that spin-rotation interactions provide the other major relaxation mechanism.
