 Title    Simplified Non-Empirical Unrestricted Hartree-Fock Approximation (SUHF) for the Calculation of Electronic Ground State Properties of Molecules with Closed and Open Valence Shells. II. Diatomic Molecules  
 Abstract    A comparison of numerical Simplified Unrestricted Hartree-Fock (SUHF) results (electronic ground state configurations, total energies, first ionization potentials, atomic charges, atomic spin densities of diatomic molecules) with those of equivalent standard calculations suggests the appli-cability of the non-empirical but drastically simplified procedure. SUHF may even approach ab ini-tio quality obtained with simple (STO-3G) contracted Gaussian basis sets.
