Abstract
First-principles calculations identify edge-bridging O adatoms as the source of the vibrational loss observed for step-adsorbed O on Pt(533), and by implication, of the scalloped appearance, in scanning tunneling microscopy of O-saturated -type island edges on Pt(111). Further calculations for O/Pt(221) provide an opportunity to confirm that O adatoms prefer upper-terrace fcc hollows at a -type step.
