Abstract

The tetrameric Mn cluster in PS II is believed to provide a catalytic site for oxygen evolution that is one of the key biochemical reactions on the earth. In spite of extensive efforts, however, little is known on the mechanism of the oxygen evolution and the structure of the Mn cluster [1]. Since a Mn ion has both electric and nuclear spins, EPR spectroscopy is advantageous for the elucidation of the magnetic/electronic structure of the cluster. Here, we present the results of simulation studies of oriented S2-state multiline spectra and spin-exchange structures of the S2-state Mn cluster on the basis of the obtained effective55 Mn hyperfine tensors.
