Abstract
The optically forbidden 1Σ+→a3Π transition of CO adsorbed on an epitaxially grown Al2O3 (111) surface has been studied by means of electron energy loss spectroscopy. On this surface several CO adsorption states exist with adsorption enthalpies ranging from 88 (multilayer) to 170 meV. For the first time even in the (sub) monolayer range the vibrational fine structure of the energy loss peaks due to the 1Σ+→a3Π electronic transition of adsorbed CO could be clearly resolved. The half widths of the loss peaks have been used to estimate the lifetimes of the excited states.
