✦ Synopsis


Rayleigh-Schr6dinger perturbation theory including exchange based upon an unpartitioned Hamiltonian and properly symmetrized vs has been applied to the ground and the first excited state of the hydrogen molecule ion. Expansion of the first-order function in terms of two-centre linear pseudostates involving powers of confocal spheroidal coordinates rapidly converges to highly accurate results for both states.
