Abstract:

Electron energy-loss results are presented which permit the detection of up to the fourth vibrational state of the CH stretching vibrations of benzene and pyridine adsorbed on Ag111. A reduced anharmonicity is observed for adsorbed benzene while both alpha and beta, gamma-CH groups for pyridine can be observed. The life time for the V0 yields 4 vibrational excitation of benzene is estimated to be 2 x 10 to the -14 power sec.
