    • In fact, the charge-separated states in 4 and 5 have relatively high energies, so that back electron transfer to the ground state is expected to occur in the Marcus inverted region and can be relatively slow. From an electronic viewpoint, charge recombination to the 3MLCT state, i.e. the process denoted as EQ in Fig. 6, involves orbitals that are spatially close to one another, whereas charge recombination to the ground state (CR in Fig. 6) would involve a metal-centered orbital as the acceptor partner, with a reduced electronic coupling for the process as compared with EQ and CS processes. A cursory look at Fig. 6a should better clarify this issue.
