The cell effect in adamantane adsorption on graphitized thermal carbon black

Nonequivalence of the nodal and bridging carbon atoms of the adamantane mol ecule during adsorption on graphitized thermal carbon black was shown. The nonequivalence is related to a special type of intermolecular interaction, the cell effect. Based on the experimental data and the molecular statistic al calculations of Henry's constants, the parameters of atom-atom potential s for the nodal carbon atoms in the adamantane molecule were found. This at om-atom potential differs from that known for the carbon atom in the sp(3)- hybridization.
