Abstract

original image

Höchst detailliert lassen sich die elektronischen Strukturen von Adsorbaten mit einer Kombination aus hochauflösender Röntgenphotoelektronenspektroskopie und dichtefunktionaltheoretischen Methoden untersuchen. Mithilfe dieser Technik wurde gezeigt, dass die Adsorption von Ethylenoxid auf einer Ag(111)-Oberfläche zu einem unsymmetrischen Oberflächen-Oxametallacyclus führt (siehe Bild).
