In spite of its model character , the mechanism of the photoionization described here has received very little attention. It is demonstrated that the electronically excited species *[Ru(bpy) 3 ] 2+ acts as a catalyst, and is regenerated in its excited state by a photoreaction of the ionized ruthenium complex [Ru(bpy) 3 ] 3+ with water (see catalytic cycle; bpy=2,2′‐bipyridine).
