Abstract
In the N-2/Xe/Pt(111) physisorption system, differences between N-2 va lence orbitals parallel and perpendicular to the surface are demonstra ted by polarization-dependent vibrationally resolved autoionization sp ectroscopy and calculations using a self-consistent image charge model . The adsorbate-substrate interaction is shown to affect the intramole cular bonding. The results disagree with the ''hole hopping'' model re cently introduced in order to explain the differences in the valence p hotoemission vibrational progressions between free and physisorbed mol ecules.
