An orbital approach of electron transfer in multisite systems. Implications for carbon-rich spacers

Isolobal analogy between organometallic and organic sites; link with solid-state concepts. Electronic interaction through overlap of “magnetic-like” orbitals: decay of the HOMO of fragments with distance, case of even and odd bridges, and aromatic linkers. Electron-phonon interaction (Holstein and Peierls types). A three-state model for M-L-M systems.
