A large solvent polarity effect on the rate of singlet to triplet intersystem crossing (ksT) has been observed in the carbenes, diphenylcarbene (DPC) and dicycloheptadienylidene (DCHD)-it is found that both ksT and the energy splitting (A&T) separtaing the singlet and triplet states decrease as the

โฆ Synopsis
The intersystem crossing decay constants from the 3Bzu state into the ground state of anthrauxeil~o in a phenzzine crystal have been determined by magnetic resanmae techniques nt lSยฐK both nt hisI_ magnetic field and, by a parameterization procedure, at zzo magnetic fie!d, A comparison of the anthracenetila zero4icld resuIts with those for anthracene-hlo show the effects of deuterium substitution to be largest for the in-plane spin levels of the anthraene triplet state.
