Abstract
Inelastic electron scattering from the vibrational modes of benzene chemisorbed on Pd(100) and Pd(111) at room temperature show energy-dependent structure and mode selectivity. The results are characteristic of resonance scattering via temporary negative-ion states. We observe resonance behavior in the totally symmetric C-H stretching mode and its overtones, (n=1,2,3), near 2.5 eV impact energy, and associate it with a gas-phase benzene resonance at higher energy.
