THE CHEMICAL HAMILTONIAN APPROACH  (CHA)

  1. INTRODUCTION

    The two alternative treatments of the Basic Set Superposition Error (BSSE) problem of molecular interaction - the a posteriori counterpoise (CP) correction scheme of Boys and Bernardi (BB Molecular Physics 19, pp553 1970) and the a priori exclusion of the basic-set superposition error (BSSE) by using the "chemical Hamiltonian approach" (CHA). The basic idea of the a priori exclusion of the BSSE was formulated by ISTVÁN MAYER in 1983 (International Journal of Quantum Chemistry, vol. XXIII, 341 - 363, 1983), and was successfully applied in the intermolecular interaction calculation.
