Abstract

The adsorption structure of methylthiolate ([Formula presented]) adsorbed on Au(111), a long-standing controversial issue, has been unambiguously determined by scanned-energy and scanned-angle S [Formula presented] photoelectron diffraction. The methylthiolate molecules are found to occupy atop sites with a S-Au distance of [Formula presented]. The angular distribution of the S [Formula presented] photoelectrons due to forward scattering reveals that the S-C bond is inclined by approximately 50° from the surface normal towards both the [Formula presented] and [Formula presented] (nearest-neighbor thiolate) directions.
