Abstract/Artist Statement
The fluorescence quenching of Tris(2,2’-bipyridyl)ruthenium(II) cation by iron (III) and copper (II) has been studied at room temperature in aqueous 0.5 M sulfuric acid. Under these conditions, the Stern-Volmer constants Ksv are determined to be 734 1/M for iron (III) and 25.8 1/M for copper (II). These are diffusion controlled processes, and the quenching rate constants and the self-exchange rate constants for the cations are analyzed in the context of Marcus theory..
