    • The program SPECFIT. described by Maeder, was modified by Dr. R. A. Binstead to perform kinetic analyses. The authors thank Dr. Binstead for performing this analysis. The time-resolved emission spectrum for [Ru(bpy) 3]2+* was subjected to the global analysis procedure described by Maeder and Zuberbuhler54 which showed that emission decay kinetics were independent of wavelength and the emission maximum invariant with time. The calculated spectra from the global analysis procedure by using the Williams-Watts equation were in excellent agreement with observed spectra

    • As noted below, emission decay is nonexponential and there can be a contribution from an impurity, notably [Ru(bpy)3](PF 6)2. The difficulty in avoiding this impurity has been discussed previously.31 The presence of a stable emitting impurity can be ruled out based on the following observations: (1) Decay kinetics were independent of exciting or monitoring wavelength, which argues against a mixture of two emitting species, 2) The excited state lifetimes obtained from the biexponential fits (eq 4) to the emission decay of cis-[Ru(bpy) 2(py)2]2+* were significantly shorter than the lifetime of [Ru(bpy)3]2+* under similar conditions, 3) There was no detectable room-temperature emission from cis-[Ru(bpy)2(py)2](PF6)2 and trans-[Ru(bpy)2(4-Etpy)2(PF6)2 salts in Ar-sparged 4:1 (v/v) EtOH/MeOH
