B Electron Configurations

Figure 15.4. (a) Frontier orbitals of the fragments (b) electronic configurations with two electrons (c) order of the energies of the electronic states. 

Figure 4. HOMO/LUMO scheme for operation of a proposed molecular shift register [48]. a) The clock cycle is initiated by photoexcitation of the donor moiety, resulting in the electronic configuration shown. Decay pathways from this excited state are forward electron transfer within the same monomer unit (solid), back electron transfer to the adjacent monomer unit (dash-dot), and fluorescence (dot), b) Electronic configuration resulting from successive forward electron transfer steps. The charge-separated state [D -Ai-A2 ] can recombine charge within a single monomer unit (dot-dash) or with the adjacent monomer unit (solid).
