Further theoretical calculations have been carried out for the adsorption potentials of Ar on the (011) face of rhombic sulfur, and for Xe and SF 6 on the (011) and (111) faces. By using the same sites for the three molecules and pair‐potentials of the Lennard‐Jones type, specific scaling factors were found. These are constant within 5–10%, for each adsorbate, and therefore the distribution curves of the adsorption potentials of simple molecules on crystalline sulfur are related in a simple way. The influence of the size of the molecule and the local geometry of the surface is also discussed.
