Vibrational Overtone Spectroscopy of Benzene and Pyridine on Ag(111).
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 Ag(111). 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 V=0 yields 4 vibrational excitation of benzene is estimated to be 2 x 10 to the -14 power sec.
