Abstract

Large quantities of nitrogen adsorb after the gas is atomized by a high-frequency discharge on both surfaces. The total coverages reached a half monolayer with respect to the surface metal atoms. An ordered LEED pattern was not observed during the adsorption on Cu(111). A small amount of adsorbed N (2 multiplied by 10**1**4 atom/cm**2), however, produced a (2 multiplied by 2) LEED pattern on Pt. A larger quantity of adsorbed N, similarly to the adsorption of CO, induced a (1 multiplied by 2)-(1 multiplied by 1) change in the periodicity of the reconstructed Pt surface. Nitrogen desorbed from Cu(111) surfaces in two stages, with one peak maximum which shifted from 620 to 700 K with increasing coverage ( beta //1 state), and with another peak at 773 K ( beta //2 state). Activation energies for desorption were 29, and 36 kcal/mol. Nitrogen desorbs from Pt(110) in only one stage, with a peak at 443 K. The activation energy is 25 kcal/mol.
