## Abstract The existence of two independent chromophores in [Ru(bipy)~2~(H~2~V)]^+^, where H~2~V^−^ = violurate anion and bipy = 2,2′bipyridine, was demonstrated by comparing its resonance Raman spectra with those displayed by the [Ru(H~2~V)~3~]^−^ analogue. In the former, the electronic band at 4
The temperature dependence of the emission lifetime of the series of complexes Ru(bpy),(4,4'-dpb): ? (bpy = 2,2'-bipyridine, 4,4'-dpb = 4,4'-diphenyL2,2'-bipyridine) has been studied in propionitrile/butyronitrile (4:5 u/u) solutions in the range 90-293 K. The obtained photophysical parameters show
