Numerical Hartree–Fock calculations on diatomic chromium

Numerical restricted Hartree–Fock (RHF) calculations on diatomic chromium have been carried out with the partial‐wave procedure. The results are compared with the large Slater basis results of McLean and Liu. Most of the residual error in their largest basis is shown to be asymptotic error in the energy of atomic chromium. The true molecular error is small and has little effect on the spectroscopic properties of the molecule at the RHF level.
