Abstract
The molecular adsorption and desorption of ferrocene, Fe(C5H5)2, on Ag(100) have been studied by both photoemission and thermal desorption. Photoemission results indicate that the initially adsorbed surface species closely resemble that of molecular ferrocene. The molecule is adsorbed with the cyclopentadienyl (C5H5) ring ligands parallel to the surface, as determined by electron energy-loss spectroscopy. The shift in photoemission binding energies relative to the gas phase is largely independent of the molecular orbital. The ultraviolet light does lead to partial fragmentation of the ferrocene, but fragmentation occurs only in the presence of incident radiation. The energetics of molecular desorption are influenced by lateral interactions within the molecularly adsorbed film.
