Molecular associations from ab initio pair potentials. A method of building up stable molecular associations by using pair potentials from ab initio calculations is presented. The Matsuoka-Clementi-Yoshimine potential has been chosen to emulate the water-water interactions while 1-6-12 potentials are used to compute both solute-solvent and solute-solute interactions. Parameters for neutral-amino-acid-water and neutral- amino-acid-neutral-amino-acid interactions are provided by the program. Supermolecules are constructed by minimization of the interaction energy of the molecules involved. Both steepest-decent and Fletcher-Powell algorithms are available to carry out such a minimization.
