Chemisorption on Transition-Metal Surfaces: Screening and Polarization versus the Intra-adsorbate Coulomb Interaction

Abstract

It is shown that a correct interpretation of the spectroscopic data for most chemisorbed systems implies the existence of considerable screening and polarization effects. A specific view of chemisorption on transition metals is suggested, incorporating the importance of the metallic nature of the substrate as well as the effect of the local environment of the adsorbate.
