Underpotential deposition and dielectric electronegativity scale

The in situ differential reflectance spectrum of a polycrystalline gold electrode in 1 mol dm -3 HClO 4 solutions as a function of coverage of Pb, Ag and Cu adatoms, has been measured in the visible region. The optical response of the metal modified surfaces was analysed through correlations with pa...
