4T2→2E Intersystem-crossing efficiency in the Cr(bpy)33+ and Cr(phen)33+ ions in aqueous media
Abstract
Comparison of the photoaquation quantum yields of Cr(bpy)33+ and Cr(phen)33+ complexes in alkaline aqueous media, from direct irradiation into the spinallowed 4T2 manifold and into the spin-forbidden 2T1/2E states, indicates that the 4T2→2E intersystem-crossing (isc) yields are identical for the two complexes (ηiscca. 1).
