✦ Synopsis

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 (\frac{5}{2}) with EPR spectrum characteristics determined by nearly rhombic symmetry of the crystalline field. c. 1994 Academic Press, Inc.

## Abstract The ligand (N^1^‐[3‐(2‐aminoethylimino)‐1,1‐dimethylbutyl]ethane‐1,2‐diamine), L^1^, induces a high ligand field on the central Ni^II^ ion. Thus it is relatively easy to oxidize(Ni^II^L^1^)^2+^. However, the kinetic stability of the Ni^III^L^1^ complexes is considerably lower than that
