Time-resolved resonance Raman (TR/sup 3/) spectroscopy has recently evolved as a powerful tool for the investigation of the dynamics and structures of a variety of reactive intermediates, electronic excited states, biological systems, and enzyme-substrate complexes. In this communication, the authors report the TR/sup 3/ spectra of three ruthenium complexes of special importance because of three ruthenium complexes of special importance because of their binding ability to nucleic acids, because of their success as chiral probes that recognize the conformations and helicity of nucleic acids, and because of their potential to serve as models for the interaction of metal ions with nucleic acids. They report here the results of TR/sup 3/ and transient absorption experiments which demonstrate that the excited states of three Ru(II) complexes, tris(2,2'-bipyridyl)ruthenium(II) dichloride (I), tris(1,20-phenanthroline)-ruthenium(II) dichloride (II), and tris(4,7-diphenyl-1,10-phenanthroline)ruthenium(II) dichloride (III), are indeed localized on the ligand.
