Fig. 9 The HF/3-21G HOMO and LUMO of the rigid benzoquinone-6-aniline donor acceptor system. The HOMO is associated with the aniline donor and the LUMO with the benzoquinone acceptor. These MOs are the active orbitals involved in optical ET in this molecule (see Fig. lb). Note that the benzoquinone LUMO is not entirely localised within this group, but extends into the bridge, by a hyperconjugation mechanism, the LUMO amplitude decaying exponentially with increasing penetration into the bridge. This type of orbital extension is also observed for the aniline HOMO. Fig. 9 The HF/3-21G HOMO and LUMO of the rigid benzoquinone-6-aniline donor acceptor system.
