    • If Coulson-Fischer localized MOs (for example, π(SN) = a + k′b rather than AOs are used to accommodate the electrons that form the (fractional) electron-pair S-N or S- S π bonds in the increased-valence structures XXI-XXIV, then the wave function for resonance between a pair of increased-valence structures involves four independent variational parameters (k′, k″, l′, and l″). When these parameters are chosen variationally, resonance between the associated pair of increased-valence structures is equivalent to resonance between the 10 Lewis structures of Tables 2 and 3.

    • 2 need also to be included so that, for the same AO basis, the resulting five-configuration MO wave function is equivalent to the variationally best VB wave function for resonance between 10 Lewis structures.
