Determination of the orientation of naphthalene molecules on Pt(111) by packing energy calculations

Using LEED information on the structure of naphthalene on Pt(111) [see K.J. Rawlings et al., Surface Sci. 109 (1981) L513 and references therein] the packing energy of the adsorbate monolayer is calculated by use of nonbonded potential functions, and the symmetry of the monolayer and the best molecular orientation are obtained.
