Fascinating Aspects of Tunneling Reactions in Organic Substances subjects of hydrogen-atom or hydrogen-molecule tunneling will be described in this chapter. The first subject is a highly selective reaction by use of a tunneling reaction. A selective reaction is one of the significant targets in chemical synthesis in order to obtain only one desirable product. In

Atom Tunneling and Molecular Structures (Bountis 1991). Proton transfer dynamics have been extensively studied, and it has been shown that proton transfer cannot be well described by a one-dimensional potential along the reaction coordinate in many polyatomic molecules. When a potential barrier exists along the reaction coordinate the m

Atom Tunneling Phenomena in Quantum Solid and Liquid HeliumIn general, the tunneling rate of a particle depends strongly on its mass and the potential height. Since the mass of the electron is very small, there are many examples of tunneling phenomena in electron systems, for example, field emission from a metal surface and the Josephson tunneling of superconducting electron pairs through a weak link.
