SIMPLE SHORT-RANGED MODELS OF WATER AND THEIR APPLICATION - A REVIEW

Simple molecular (statistical mechanical) models of water and their pr operties, with the emphasis on a class of so called 'primitive models' , are reviewed. These models are based on the finding that the structu re of water is determined primarily by short-ranged (both repulsive an d attractive) forces and do not incorporate thus any long-ranged elect rostatic interactions. Considerable attention is paid to the physical footing of the models and to their potential in applications and for d eveloping a first-principle theory of water and aqueous solutions of n onelectrolytes.
