Dyson pole strengths

E Ag for D2h molecules and X B2, A A], B B2, C Bi, D Ai and E Ai for gallaborane. Pole strengths near 0.9 for the first five ionization energies in each molecule indicate that the Koopmans description of the final states is qualitatively valid. Only for the E states is there significant multiconfigurational character. Each of the Dyson orbitals for these ionization energies is dominated by a single, canonical, Hartree-Fock orbital.
