Following Re 1 → 4,4'-R 2 bpy metal-to-ligand charge transfer (MLCT) excitation, intramolecular electron transfer leads to the transients, fac-[(4,4'-R 2 bpy)Re I I (CO) 3 (LA . - )] n + . They have been characterized by emission spectral fitting and transient absorption measurements and, for LA = OQD, by transient infrared measurements. As shown by analysis of excited-state
