The adsorption potentials of argon on the (111), (001) and (110) planes of rhombic sulfur have been calculated for a total of 818 sites, using an intermolecular potential of the Lennard ‐ Jones (6:12) type with the Kirkwood ‐ Müller expression. Direct summation over the nearest 100–150 atoms of the solid was used. There is a good agreement between the experimental and the calculated values of the adsorption potential, as a function of the surface coverage.
