    • note
    • From the PMO approach, the anion 1 is regarded as formed by replacement of one CH-group in benzene by NH-group and by addition of one electron, whereby a degeneracy of the LUMOs in benzene is lifted. The extra two ;r-electrons are assigned to the resulting LUMO with large atomic-orbital coefficients on two opposite positions and, as a result, C4 has a large negative charge. Indeed, the atomic population of 6.8773 is made up of the and π components of 5.1825 and 1.6948, respectively.
