โœฆ Synopsis


Raman and luminescence spectra of Ru(bpy)$+ showed changes in frequencies and intensities in anionic micelles only. The data are interpreted in terms of the localization of the optical electron in a bipyridine ring that is some distance from the negative micellar surface.

Excited-state resonance Raman (ERR) spectra of Ru(bpy)32+ in solid phases show a broad continuum in the 1500 cm -1 region of the excited-state 2,2'-bipyridine (bpy) ring modes. Studies of 1 : 1 water/glycol mixtures above and well below the glass-forming temperature lead to disappearance of the disc
