N2 - Near-edge x-ray-absorption fine-structure spectroscopy studies are used to determine changes in the electronic, geometric, and magnetic structure of two sequential molecular precursors of O2 on Pt(111). Both molecules lie down on the surface. Physisorbed O2 is found to be van der Waals bonded, structurally unperturbed and paramagnetic, while chemisorbed O2 is e bonded, stretched by 0.16, and exhibits a reduced or vanishing paramagnetic exchange splitting.
