Four-component, second-order Dirac-Slater calculations are reported for LiH, Liz, BH and CH+. Relativistic corrections to the total energies, bond lengths, vibrational frequencies and electric multipole moments are given. Dirac-Pock results are presented for Hz. The origin of the relativistic bond c

✦ Synopsis
A fully numerical Hartree-Fock approach is developed for diatomic molecules. The eschange potential is solved reltiittg a local, Poisson-like equation. Improved Hattree-Fock limits are reported for LiH and BH.
