increase with increase of free energygap, −ΔGBET, between the ground state CT complexes and the resulting radical ionpair (RIP). These observations can be rationalized by a mechanism involving a distinctive RIP as an intermediate generated by photoinduced electron transfer in each mode. Thus, the solvent-separated radical ionpair (SSIP) produced in the direct mode excitation will undergo dissociation
