✦ Synopsis

Triplet electron transfer is observed in a covalently linked porphyrin-quinone in ethanol at temperatures between 160 and I30 IC. Both, the primary porphyrin triplet state 'P-Q and the radxal pair (+P-Q-)T created by light-induced charge separation, are observed by time-reaclved EPR. The latter is identified by its gfactor and dipolar splitting.
