We discuss the solution of the integral Dirac–Fock equation in momentum space. “Balanced” momentum‐space gaussian functions are used to expand the large and small components of the Dirac 4‐spinors. We show that this approach, which has been successfully used in atomic Dirac–Fock calculations, works equally well in molecular Dirac–Fock calculations.
