摘要：

Resonance Raman (RR) and time-resolved resonance (TR3) methods are used to investigate the electronic structures of the ground and lowest excited states of heteroleptic complexes of Ru2+ with bipyridine and bipyrazine. The spectra of the ground-state species permit assignment of the electronic absorption bands to specific metal-to-ligand charge-transfer transitions. The TR3 results document specific population of bipyrazine-localized excited states in the heteroleptic complexes. In addition, the present studies provide support for the original interpretation of the TR3 spectrum of Ru(bpy)32+ by Dallinger, Woodruff, and co-workers. © 1990 American Chemical Society.
