Part i: we have investigated the efficacy of ab-initio effective potentials in replacing the core electrons of atoms for use in molecular calculations the effective potentials are obtained from ab initio gi calculations on atoms and are unique and local we find that the use of these effective potentials to replace the core orbitals of such molecules as lih, li_2, bh, or lih_2, leads to.
