An associative version of the Henderson-Abraham-Barker equation

Abstract
An associative analogue of the Henderson-Abraham-Barker equation and its analytical solution for the Wertheim's dimerization model with a hard wall is obtained. The dependence of the adsorption on the bulk density η and on the dimerization constant K is investigated. It is shown that the shape of the density profile allows one to draw some conclusions about the dimer orientation.
