Near edge X-ray absorption fine structure (NEXAFS) spectra were measured and analyzed to reveal the adsorption structures of NO on Pt(111) at 290 and 230 K. N K-edge NEXAFS spectra show a single π* resonance at 290 K, while they exhibit double peaks at 230 K. Simple polarization analysis cannot be applied to such a complicated system. Simulations based on the multiple scattering theory confirmed that NO is uniquely adsorbed at the hollow site at 290 K and there are two kinds of adsorption species at 230 K: one at atop site with a tilt angle of about 50° and another at hollow site with upright direction. They are in close agreement with the results by recent LEED I/V analysis.
