Abstract
Low-temperature HREELS data of NO adsorbed on a Ag(111) surface are an alyzed with the help of LCGTO-LDF cluster models. It is shown that the loss peaks observed at 143 and 159 meV are due to stretching vibratio ns of negatively charged nitrosyl species bound upright via the oxygen atom at threefold hollow (mu3) octahedral and tetrahedral sites, resp ectively. Bent structures of the adsorbate are energetically less favo red both for the mu3-ON and for the mu3-NO adsorption complex.
