The luminescence and magnetic circular polarized luminescence (MCPL) spectra of Ru(bpy)2+3 in poly-(vinyl-alcohol) solid solutions are analyzed in terms of a three level model of the lowest excited states. The individual luminescence and MCPL profiles of the three states are obtained, for the first time, by careful deconvolution of the temperature dependent spectra. The temperature dependence of the MCPL spectra in the 1.5–60 K range can be quite accurately accounted for by the superposition of strong (temperature independent) B terms from each of the states of relative magnitudes (approximate)4:1:−0.1. A comparison of the very different luminescence and MCPL spectral profiles of the transitions arising from the three individual states provides insights into the unusual and apparently vibronically induced processes dominant in Ru(bpy)2+3 luminescence for all three electronic states.
