Infra-red spectra and dimerization of NO adsorbed on lithium halide films

Abstract

Infra-red spectra of NO adsorbed at different surface coverages on high-surface area films of LiF, LiCl, LiBr and LiI are described. The spectra are interpreted in terms of dimers adsorbed on sites located in the surface planes and on the crystallite edges. Heats of adsorption of single NO molecules were calculated for different adsorption sites and orientations of the adsorbate and compared with the experimental values.
