摘要：

Angle resolved photoemission spectroscopy using synchrotron radiation has been applied to study a (3 × 3) overlayer of benzene adsorbed on Ag(111). This monolayer is formed by flat lying benzene molecules. The photoelectron spectra can only be interpreted if the surface molecule is described by C3v,σd symmetry. The adsorbed benzene molecules exhibit an almost uniform relaxation shift of the ionization potentials of 0.8 eV comparing adsorbed and gaseous phase. Combining the photoemission and LEED results a structural model is proposed, in which the benzene molecules occupy the three-fold hollow sites of the Ag(111) surface. © 1990.
