We have investigated resonance electron scattering by both physisorbed and chemisorbed molecular O2 on Pt( 111). In each case, the molecular &-shape resonance is manifest in the vibrational excitation cross section but the resonance energy is lowered in comparison with the free molecule. We attribut

The Y = 0 + 1 vibrational excitation function for 0, chemisorbed on a Pt(ll1) surface is reported for the incidence electron energies l-9 eV. This measurement, combined with experimental results for chemisorbed O,/Pd(lll) previously reported in the literature, shows the presence of the 30: resonance
We have measured the electronic structure of O2 chemisorbed in a x-bonded configuration on Pt ( 111) at 100 K. The positions of the inner valence levels of the adsorbate are extremely sensitive to the molecular adsorbate bond length. Comparing the measured binding energies of the three innermost o-v
