Adsorption structures of NO molecules on a Pt (111) surface at low temperatures have been studied using low-energy electron diffraction (LEED). At 150 K a 2 × 2 LEED pattern appears at exposures higher than 0.2 L. With increasing exposure, the LEED spots get sharper, indicating two-dimensional island growth of adsorbed NO. The LEED I-V spectra measured at 0.4 L are different from those at 3 L, suggesting the presence of two kinds of 2 × 2 structure. The LEED I-V analysis performed for the 2 × 2 at 0.4 L strongly supports that NO is adsorbed at a threefold fcc hollow site. For the I-V curves of 2 × 2 at 3 L, the fcc hollow site model calculation does not fit the experimental I-V curve, suggesting that a different 2 × 2 structure grows after the first 2 × 2 structure is completed.
