Kinetics model of photoinduced electron transfer in ReI(CO)3(dmp)(His124)|(Trp122)|AzCuI. Light absorption produces electron and hole separation in the MLCT-excited ReI complex. Vibrational relaxation of *Re occurs in ~100 ps, followed by migration of the hole to CuI via (Trp122)•+ in less than 50 ns. Charge recombination proceeds on the microsecond timescale. Elementary rate constants were extracted from fits to time-resolved luminescence, visible absorption, and infrared spectroscopic data.
