| Metal-to-Ligand Charge Transfer (MLCT) excited states in polypyridyl complexes of Ru(II), Os(II), and Re(I) have provided the basis for innumerable studies in photochemical electron and energy transfer. The excited states themselves are electronically complex and are coupled in a complex way to the surrounding media and to metal-ligand and intra-ligand molecular vibrations. Transient infrared (TRIR) and transient near infrared (TRNIR) measurements on related families of MLCT excited states have revealed new features in the electronic and molecular structures of these excited states. When combined with the results of recent DFT theoretical calculations, the essential molecular featues that control excited state properties are being revealed. |
