Abstract
Electron transfer reactions between porphyrins and chlorophylls in their photoexcited triplet state (electron donors) and duroquinone (electron acceptor) were studied by laser excitation-Fourier transform (FT)-EPR spectroscopy (∼10 ns time resolution). This highly time-resolved EPR spectroscopy enables to differentiate between the triplet mechanism (TM) and radical-pair mechanism (RPM) which contribute to the overall CIDEP mechanism associated with the electron transfer process.
