Abstract
EPR of the Mn multiline in the S2-state of single crystals Synechococcus vulcanus has been observed at 6 K by W-band EPR spectrometer. The multiline composed of 21 lines, showing that four manganese contribute to the multiline. The hyperfine constant does not depend on crystal orientation but the positions of hyperfine lines are changing with orientation. No multiline EPR was observed in a frozen solution of the same sample. Similar spectra were observed in the S0-state reduced by NH2OH. These results are now under simulation assuming g-anisotropy.
