Abstract

Images of monolayer coverages of C60 on gold substrates, using scanning tunneling microscopy, reveal intermolecular arrangement and intramolecular features. In this paper we concentrate on the interpretation of these internal features, present a model showing that they arise from local charge density variations of high-lying π orbitals on approximately every other carbon atom, and discuss also other possible mechanisms for this effect.
