摘要：

D1/D2-cyt b559 complexes from Pisum sativum were investigated by absorption detected magnetic resonance (ADMR) in zero field. Two different triplet states were detected and further characterized by temperature dependent and time resolved ADMR, microwave holeburning studies, and the magnetic field dependence of the ADMR signals. Their microwave induced absorption (MIA) spectra showed maxima at 683 and 680 nm. They were identified as the triplet states of the primary electron donor P-3(680) and of a pheophytin a molecule possibly connected with partially degraded D1/D2-complexes. From comparison with bacterial reaction centers (RC) it can be concluded that the triplet state of the primary donor in plant photosystem II (P-3(680)) is located on a monomeric chlorophyll a molecule.
