    • This is based on the potential of the [Ru(bpy)3] 3/2+ couple that is considered to be largely solvent independent and amounts to 0.90 V versus Fc+/0 in acetonitrile 1.27 V vs. NHE in water, Potentials in nonaqueous solvents are frequently measured and reported versus the aqueous SCE. This introduces unknown junction potentials, however, and a comparison of such data with potentials obtained in other solvents like water is not meaningful even if the potentials are formally given versus the same reference electrode like SCE or NHE. Independent of this problem, electrochemical potentials are intrinsically solvent dependent and any comparison between data in different solvents can only be approximate;
