## Abstract Previous papers have developed magnetic effective valence bond (EVB) Hamiltonians for the neutral states of Ο systems; following the same philosophy and using either the quasidegenerate perturbation theory or wave operator formalism, other EVB^+^ Hamiltonians may be derived for the lowe
