Resonance Raman spectra and photoelectron transfer by visible light in the system Ru(bpy)/sub 3//sup 2 +/-MV/sup 2 +/-Na-zeolite Y are examines. The Ru(bpy)/sub 3//sup 2 +/ molecule is trapped in the dehydrated zeolite Y supercages. Upon photoexcitation of this molecule, MV/sup .+/ radical cations are formed in neighboring cages. The radical cation is stable on the hour time scale and decays by back electron transfer to Ru(bpy)/sub 3//sup 3 +/. The resonance Raman spectrum of the radical cation shows evidence of interactions with the zeolite framework.
