Zusammenfassung:	(Ru(bpy)/sub 3/)Br/sub 2/ in dimethylformamide loses one bipyridine upon irradiation at 458 nm, with an overall quantium yield of 3 x 10/sup -4/ with 0.017 M Br/sup -/ present. The quantum yields of the two photoproducts. (Ru(bpy)/sub 2/(DMF)Br)/sup +/ and (Ru(bpy)/sub 2/Br/sub 2/), are linearly dependent on bromide concentration within the range 0.0016 < (Br/sup -/) < 0.017 M. The results are consistent with a model based on ion pairs and ion triplets as the photoactive species.
