Notes:
Pseudopotentials are used for investigating the effects of relativity and correlation on atomic properties of Br and I, and on bond lengths and dissociation energies of the molecules HBr, HI, Br2, and I2. The pseudopotentials are adjusted to energies of Br6+ and I6+ on different levels of approximation: (i) to Hartree–Fock data for the nonrelativistic case, (ii) to Dirac–Fock data for the relativistic case, and (iii) to experimental energies for the relativistic case including correlation. At the highest level of approximation, atomic ionization energies, electron affinities, molecular dissociation energies, and bond lengths are obtained in good agreement with the experimental results.
