Resonance Raman (RR) and time-resolved resonance (TR{sup 3}) methods are used to investigate the electronic structures of the ground and lowest excited states of heteroleptic complexes of Ru{sup 2+} 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 TR{sup 3} 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 TR{sup 3} spectrum of Ru(bpy){sub 3}{sup 2+} by Dallinger, Woodruff, and co-workers.
