Monolayer adsorption of non-spherical molecules on solid surfaces. Part 1.—Adsorption of hard dumb-bells on flat surfaces

Abstract

In this paper the RAM-type perturbational theory is adapted to description of monolayer adsorption of linear molecules on flat surfaces. The theory is next applied to the study of a two-dimensional system of hard dumb-bells. The results are compared with computer simulations and with theoretical predictions based upon the scaled-particle theory. We also report the values of the third and fourth virial coefficients obtained using the Monte Carlo technique.
