A comparison is presented for the ground state of the helium atom of high order Rayleigh-Schri)dinger perturbation theories based upon a hydrogenic. a screened hydrogenic, a Hartree and a modified Hartree local zero-order hamiltonian. The hydrogenic zero-order schemes are superior tc the Hartree zer

The generalized Heitler-London theory has been implemented for a calculation of the ground state (X 'Cl ) potential of the Hz molecule at distances of R = 1.4 and 8.0 au. With the exact exchange energy and newly calculated accurate overlap integrals, convergence is achieved to better than 1% by expa
The electronic energy of atoms and molecules may be evaluated accurately by the use of wave functions where the interelectronic distances are explicitly present. In particular, explicitly correlated Gaussian-type functions make these types of calculations feasible and computationally tractable even
The quantum mechanical energy is examined in which groups of one, two, three, and four localized electron pairs found within a molecule are separately computed. From these results, the interaction energies of the electron pairs taken one, two, three, and four at a time form the terms of a convergent
