Title: Resonance Raman and photophysical studies of transition metal complexes in solution and entrapped in zeolites

This program is subdivided into two major categories: (1) the study of complexes of Ru(II) in fluid solution and (2) the investigation of the effects of incorporation of such complexes into organized assemblies. In the first part of this report, clear evidence is presented for the somewhat unexpected observation of quite specific localization of excited state electron density on a rather small fragment of the coordinated asymmetric bidentate ligand. Thus far, two examples of this behavior have been documented and the results will soon be submitted for publication. The second part of the report describes continuing efforts to develop effective methods for selective preparation of heteroleptic complexes within the supercages of Y-type zeolite. One manuscript has been submitted for publication and a second is now in preparation. Also described in this section of the report are Resonance Raman studies of Ru(bipyrazine){sub 3}{sup 2+} in solutions of varying concentrations of H{sub 2}SO{sub 4}; from 0 to 96%.
