The flash-induced P515 absorbance change in dark adapted chloroplasts is known to consist of several components. Joliot and Delosme [1] described a fast (phase a) and a slow rising component (phase b). The fast rising component has a rise time less than 0.5 ms. This phase is generally interpreted as reflecting the primary charge separation in the reaction centers and is attributed to the rising part of reaction 1 [2]. The slow rising component (phase b) is referred to as the rising part of reaction 2 [2] and has been subject of numerous discussions.
