Web1. The Hartree method ignores the antisymmetry requirement for the many elec-tron wavefunction. In Section 2, we will rectify this by introducing the Hartree-Fock (HF) … WebA transition state method has been proposed for the calculation of bonding energies and bond distances within the Hartree Fock Slater Method. Calculations on a number of diatomic molecules and a few transition metal complexes show better agreement with experiment than corresponding Hartree Fock results.
