Statistical mechanics of molecular adsorption: effects of adsorbate interaction on isotherms.
We investigate a simple, exactly solvable model for interacting adsorbates. From the model study, we find that (1-theta)(-1) as a function of density of molecules in bulk media can have a positive curvature only in the presence of attractive interaction between adsorbed molecules. We propose a novel experimental observable, chi. Positive chi is the sufficient condition for the presence of attractive interactions between adsorbate molecules.
