Fig. 2.

Energy values for electronic excitation and charge-separated states of (bacterio)chlorophylls and (bacterio)pheophytins in PbRC (Left) and PSII (Right), calculated using a QM/MM approach, where the interaction between electron and hole was considered quantum-chemically. Thick solid bars indicate the major intermediate states. Red solid arrows indicate major electron transfer in the active branch, and blue dotted arrows indicate the corresponding electron transfer in the inactive branch.
