For a polyatomic adsorbate it may be necessary to sum the interactions over each atom of the adsorbate molecule as well. The various values of sy in Equation 2 can, for a particular adsorbent of known crystal lattice, be calculated in terms of a single distance, z, which is defined as the distance between the center of an adsorbate atom and the mathematical plane in which lie the centers of the surface atoms of the adsorbent. 

This results means that the adsorption isotherm within the framework of the present theory m provide us of a reliable tool to obtain and interpret the adsorption configuration and lateral interactions of polyatomic adsorbates. 

In summary, an analytical approach to the multilayer adsorption isotherm of polyatomic adsorbates (k mers) in one and two-dimensional lattices has been proposed. Monte Carlo simulation support the high accuracy of the approximation. It arises that adsorbate size as well as lattice structure influence multilayering.
