Abstract

For more than a decade transient resonance Raman spectroscopy using pulsed laser excitation has been an established technique[1] for probing the excited states of metal complexes, though there are relatively few reports of true time-resolved resonance Raman (TR3) studies involving two lasers in a pump-delayed probe arrangement. Some recent examples are listed [2,3]. We have used such two laser methods on the nanosecond timescale to investigate the decay processes following metal-ligand charge-transfer (MLCT) excitation of some heteroleptic complexes of Ru(II) with the novel ligand 1,4,5,8,9,12-hexaazatriphenylene (HAT) and either 2,2′-bipyridyl (bpy), 1,4,5,8-tetraazaphenanthrene (TAP) or 1,10-phenanthroline (phen).
