The ordering in a higher-order-commensurate monolayer solid of Pt(111)-(3 × 3)-4 N2, which has coexisting physisorbed and weakly chemisorbed N2 species, is analyzed with model calculations. Density functional theory calculations are also used to evaluate properties of chemisorbed N2 in a (2 × 2) unit cell on Pt(111). The relation of these results to the orientational ordering of N2 on other metal surfaces is discussed.
