Abstract
An explicit form for the penetration integrals in CNDO theory
is developed and tested on first row diatomic molecules. It is
shown that the non-penetration integral theory CNDO/BW is more
satisfactory for predicting bond lengths and equilibrium energies
because it gives an unstable 3 ~u+ for H2, whereas introduction of
the penetration integrals makes this state stable.
