As noted previously, the relevant Dyson orbitals shown in Fig. are reminiscent of lopsided dlike orbitals, so this work is the first application of this approach to non-σ Dyson orbitals. In Fig. , () curves for the three transitions, SO( As a reminder, both methods used the aug-cc-pVTZ+5s5p5d5f basis set. We repeated the calculations with Dyson orbitals obtained using the aug-cc-pVQZ+2s2p1d1f1g basis set, with nearly identical results (not shown).
