Formation spectra of the EPR split signals from the [S.sub.0], [S.sub.1], and [S.sub.3] states in photosystem II induced by monochromatic light at 5 K

The interaction of EPR split signals from photosystem II (PSII) are reported from the [S.sub.0], [S.sub.1] and [S.sub.3] states. The formation spectra of split EPR signals induced in PSII enriched membranes are investigated.
