Representative models of oxygen evolution

Three models which have appeared recently are discussed in this section (Fig. 1). They are representative of a variety of models which have been proposed [15,16,121,124,283] and are intended to provide an illustration of current thinking on 02-evolution mechanisms. Only the essential structural features of these models are summarized in Fig. T, the details of the structural transitions involved in the S-state changes are discussed in the original publications but have been omitted for clarity.
