Websimple Ru-bpy complexes in order to gain more critical insight into the effects of electronic mixing on metal to ligand charge transfer (MLCT) excited state properties. To this end we have examined the energy dependence of the radiative rate constants and of DFT-calculated parameters for evidence of excited state/ excited state mixing. WebLigand charge transfer (MLCT) like in [Fe(bpy) 3] 2+. In this complex the charge transfer occurs from Fe(II) to the empty π* orbitals of bpy ligand.
