摘要：

First-principles calculations identify edge-bridging O adatoms as the source of the 560 cm(-1) vibrational loss observed for step-adsorbed O on Pt(533), and by implication, of the scalloped appearance, in scanning tunneling microscopy of O-saturated A-type island edges on Pt(111). Further calculations for O/Pt(221) provide an opportunity to confirm that O adatoms prefer upper-terrace fee hollows at a B-type step.
