Core-Core Repulsions Pople a al. in their CNDO and INDO methods and Yonezawa et al. in their INDO level approximation set CAB, the core-core repulsion, equal to a point charge potential, thus: CAB----ZAZB R ~ (79) where ZA and ZB are the respective core charges. Such an approximation, however, results in calculated binding energies which are too small. The reason for this may lie in the fact that the potential field in which the electrons move in a molecule is greater than that in the isolated atom; consequently, the atomic orbitals in the molecule will be more compact.
