Temperature Dependence of Nonradiative Decay

Temperature Dependence of Nonradiative Decay

The temperature dependences of nonradiative decay for the metal-to-ligand charge transfer excited states of [Re(bpy)(CO)[sub 3](4-Etpy)](PF[sub 6]) and [Os(bpy)[sub 2](CO)(py)](PF[sub 6])[sub 2] (bpy = 2,2[prime]-bipyridine; 4-Etpy = 4-ethylpyridine; py = pyridine) follow the behavior predicted by t...

Zusammenfassung:The temperature dependences of nonradiative decay for the metal-to-ligand charge transfer excited states of [Re(bpy)(CO)[sub 3](4-Etpy)](PF[sub 6]) and [Os(bpy)[sub 2](CO)(py)](PF[sub 6])[sub 2] (bpy = 2,2[prime]-bipyridine; 4-Etpy = 4-ethylpyridine; py = pyridine) follow the behavior predicted by the energy gap law. The variations with temperature can be calculated to within a factor of 2-3 by using parameters derived from a Frank-Condon analysis of emission spectral profiles. 17 refs., 4 figs., 1 tab.
