Near-edge x-ray-absorption fine-structure studies of O2 chemisorbed on Ag(110) and Pt(111) surfaces near 100 K reveal different predissociation stages of molecular oxygen. O2 on Ag(110) exhibits only a * resonance and resembles a single-bonded peroxo species. The O-O bond is aligned parallel to the surface, along the [11»0] azimuth, with a bond length of 1.47±0.05 AÌ. O2 on Pt(111) also lies down but is less perturbed from the gas phase as revealed by the presence of a * resonance and an O-O bond length at 1.32±0.05 AÌ, characteristic of a superoxo species. © 1987 The American Physical Society.
