Description	We have analyzed flash-induced period-four damped oscillation of oxygen evolution and chlorophyll fluorescence with the aid of a kinetic model of photosystem II. We have shown that for simulation of the period-four oscillatory behavior of oxygen evolution it is essential to consider the so called intermediate S-state as an initial phase of each of the Sn-Sn+1, (n = 0, 1, 2, 3) transitions. The intermediate S-states are defined as [SnYZox]-states (n = 0, 1, 2, 3) and are formed with rate constant kiSn approx. 1.5 x 106 s-1 which was determined from comparison of theoretical predictions with experimental data. The assumed intermediate S-states shift the equilibrium in reaction P680+YZ .lt.--.gt. P680YZox more to the right and we suggest that kinetics of the intermediate S-states reflects a relaxation process associated with changes of the redox equilibrium in the above reaction.
