Abstract
The lineshape of the v=0–1 vibrational mode in the high resolution electron energy loss spectrum of physisorbed O2 on Pt(111) shows discrete loss peaks attributed to a low frequency molecule-surface vibration and its overtones. The energy and angular dependence of these vibrations is consistent with the molecular negative ion resonance mechanism predicted by Gadzuk.Keywords
