First-order symmetry-adapted perturbation theory for multiplet splittings
(2020-06-25)
We present a symmetry-adapted perturbation theory (SAPT) for the interaction of two high-spin open-shell molecules (described by their restricted open-shell Hartree-Fock determinants) resulting in low-spin states of the ...
