The lineshape of the [ital v]=0--1 vibrational mode in the high resolution electron energy loss spectrum of physisorbed O[sub 2] 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.
