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