note
-
All orbitals of the "halves" that are antisymmetric vs both molecular planes can interact giving the lower-energy bonding and the higher-energy antibonding combinations that span the entire molecule. The frontier orbitals, and specifically here for the electron acceptors the LUMOs, are of main interest. For the purpose of this discussion, the HOMO-LUMO designation refers only to the π system. The nonbonding electrons are treated separately.
