Sequential and Coherent Long-Range Electron Transfer Close to resonance with Intermediate Bridge Groups, and New Perspectives for in Situ Scanning Tunnelling Microscopy of Adsorbed Metalloproteins
Three-level electron transfer follows superexchange patterns when the intermediate electronic level is off-resonance with the donor and acceptor levels. Close to resonance, new patterns emerge where the intermediate level is temporarily populated in vibrationally coherent or incoherent modes. We discuss energy and distance relations associated with such electron transfer modes.
These appear to accord with fast electron transfer in several chemical and biological systems. We also discuss some recent observations on in situ scanning tunnelling microscopy of metalloproteins and large transition metal complexes which enable, in principle, a distinction between superexchange, coherent, and sequential three-level electron transfer.
