Vibration Spectroscopy at Surfaces
Experiments using high-resolution electron energy loss spectroscopy (HREELS) allow us to probe vibrational modes at the surface. These experiments provide information about bonding within the molecule, between molecules, and to the surface, as well as insight into the structure of monolayers and multilayers. HREELS has been applied to a model system of terephthalic acid on Cu(100) to elucidate the attractive driving force behind island formation in the sub-monolayer and the structural transition during bi-layer growth (see Langmuir 2010).
