摘要：

The local registry and geometry of thiophene at sub-monolayer coverages on Cu(111) has been probed with normal incidence X-ray standing wavefield absorption (NIXSW) and near edge X-ray absorption fine structure (NEXAFS). Thiophene was found to adopt a flat geometry on the surface with the sulphur atom in an atop position. The relatively short data collection times required for the NIXSW technique were found to be beneficial when looking at thiophene overlayers which are sensitive to X-ray induced damage.
