Long-Range Electron Tunneling
Electrons have so little mass that in less than a second they can tunnel through potential energy barriers that are several electron-volts high and several nanometers wide. Electron tunneling is a critical functional element in a broad spectrum of applications, ranging from semiconductor diodes to the photosynthetic and respiratory charge transport chains. Prior to the 1970s, chemists generally...
متن کاملElectron tunneling in biological molecules*
Electron transfers in photosynthesis and respiration commonly occur between protein-bound prosthetic groups that are separated by large molecular distances (often greater than 10 AÊ ). Although the electron donors and acceptors are expected to be weakly coupled, the reactions are remarkably fast and proceed with high speci®city. Tunneling timetables based on analyses of Fe/Cu to Ru electron-tra...
متن کاملLong-range electron transfer.
Recent investigations have shed much light on the nuclear and electronic factors that control the rates of long-range electron tunneling through molecules in aqueous and organic glasses as well as through bonds in donor-bridge-acceptor complexes. Couplings through covalent and hydrogen bonds are much stronger than those across van der Waals gaps, and these differences in coupling between bonded...
متن کاملEmpirical Protocols for Mediating Long-Range Coherence in Biological Systems
This work updates Bioelectrochem Bioenerg 41:1 (1996) 39-42, The production of Frӧhlich and Bose-Einstein coherent states in in vitro paracrystalline oligomers using phase control laser interferometry. Delineating the framework for a fundamental model of long-range coherence in biological systems is said to rely on principles beyond parameters addressed by current physical science. Just as phen...
