Abstract
Interest in ruthenium polypyridal complexes stems from the metal-to-ligand charge transfer state (MLCT) that can be generated by photons of sufficient energy and the interligand electron transfer (ILET) that occurs after this state. Direct measurements using picosecond resonance Raman spectroscopy were made to determine the rates of ILET in a series of mixed ligand ruthenium polypyridal complexes. To perform these studies, a novel regenerative amplified Nd:YAG laser system had to be designed and built at Louisiana State University. Once this system was completed, a apparatus was designed for measuring transient absorption spectra in the 200--300 nm wavelength range on a picosecond time scale. Finally, the first one color picosecond resonance Raman spectra for the ruthenium 1,10-phenanthroline complex is presented. While no rate for ILET could be accurately determined for this molecule, an accurate assignment of excited state and ground state bands is presented.
