摘要:
A light-induced g = 4.1 EPR signal of the manganese cluster in the oxygen-evolving complex of plant photosystem II was investigated by an electron-spin-echo method. The dependence of the ESE signal amplitude on the intensity of the microwave magnetic field H-1 was consistent with the model assuming a manganese electron spin of 5/2 with EPR spectrum characteristics determined by nearly rhombic symmetry of the crystalline field.
