Screened potentials of the site-site ion-molecular model

Abstract

The solution of the site-site Ornstein-Zernike equation for the ion-molecular system, which consists of positive and negative charged hard spheres and symmetrical polar molecules is obtained in the framework of the mean spherical approximation. The analytical expressions for the site-site screened potentials are calculated using the zero-pole approximation. The analysis and the numerical investigation of screened site-site potentials is carried out.
