The underpotential deposition of Cu on Au(110) has been monitored by Reflection Anisotropy Spectroscopy (RAS). The changes in the intensity of spectral features observed at 2.6 eV and 3.4 eV in the RA spectrum of Au(110) that are induced by the deposition of Cu occur on different timescales. It is suggested that these changes arise, respectively, from the partial quenching of surface states and from changes in surface morphology. (© 2005 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
