Abstract

The hydrogen bond has been under intense scrutiny in physical and chemical systems since its definition by Latimer and Rodebush in 1920 /1,2/. Investigations in biological systems, however, are of much more recent vintage. Indeed, the pioneering investigations of Löwdin /3/ were among the first attempts to characterize the role of protonic motion in hydrogen bonds in the properties of biological macromolecules. In particular, Löwdin /3/ stressed the importance of proton tunneling, and showed that this provides a mechanism for transfer and for loss of information stored in the form of proton position in a double well. Recent experimental advances, particularly in the area of picosecond spectroscopy /4/, have made it possible to experimentally observe the motion of molecular subunits, and the promise of being able to delineate the tunneling process has reemphasized the need for an understanding of the dynamics of protons in hydrogen bonds.

    M.D. Harmony, Chem. Soc. Revs. 2, 211 (1973). It must be remembered that the considerations of Harmony and of Brick-mann /12/ apply only to rigourously one-dimensional potentials. For real hydrogenbonded systems, the coupling results in a finite width for the localized double well states, and the tremendous reduction of tunneling rate for small asymmetrics predicted by (5) does not occur. Indeed, the “downhill” tunneling in these systems should be faster than the symmetric tunnelings essentially because the argument of the negative exponential in the JWKB expression is reduced by the asymmetry (A. Aviram, P.E. Seiden and M.A. Ratner, to be published).Google Scholar
