Heavy Atom Effects in Proton Tunneling Phenomena

  • Richard L. Redington
Part of the NATO ASI Series book series (ASIC, volume 483)


Intramolecular H tunneling is often analyzed using 1-D theoretical models, or improved models providing a minimum energy pathway defined by model 2- or 3-D PEFs, or models coupling a 1-D tunneling coordinate to a vibrational bath representing all other modes. The analysis of a tunneling coordinate strongly coupled to one or two heavy atom vibrational modes is of much current interest. This problem, which includes heavy atom vibrational-assisted H tunneling, is experimentally accessible to the methods of low-temperature spectroscopy on molecular beam, matrix-isolated, and solid state samples. Heavy atom effects on intramolecular H tunneling, primarily as observed by optical spectroscopy, are considered in this discussion.
