The photoracemization of Ru(bipy)₃⁺⁺ in aqueous solution was studied. Quenching studies show the involvement of the (CT)³ Ru(bipy)₃⁺⁺ in the mechanism of racemization and the low quantum yield (2.9 x 10⁻⁴) shows that this state is asymmetric. Quenching studies show no increase of racemization rate for Ru(I) or (III) species. The temperature dependence gives evidence for a dissociative racemization mechanism. Quenching with Co(acac)₃ shows chiroselective electron transfer as measured by the resulting photochemistry. / Science, Faculty of / Chemistry, Department of / Graduate
