In answer to Professor Hess, I would add that the experiments of B. Chance and R. de Vault [see, for example, Biophys. J., 6, 825 (1966)] were probably the first to demonstrate the high importance of electron tunneling in low-temperature chemical (even biochemical) processes.

A great role in substantiating the importance of electron tunneling reactions was played by the work of De Vault and Chance in 1966 where the characteristic time, t1/z, of electron transfer from the heme site of the cytochrome molecule to the chlorophyll molecule in a bacterium was shown to be constant within the temperature range of 130 to 4.2 K [4]. The temperature independence of t1/2 permitted one to reject a diffusion mechanism for the process. However, it was still impossible to exclude the possibility of the reaction to proceeding via direct contact between the active sites of the reacting molecules.

As an illustration of these considerations, the Arrhenius plot of the electron transfer rate constant, observed by De Vault and Chance [1966], is shown in Figure 2.11. Note that only Er, which actually is the sum of reorganization energies for all degrees of freedom, enters into the high-temperature rate constant formula (2.66). At low temperature, however, to preserve Er, one has to fit an additional parameter a>, which has no direct physical significance for a real multiphonon problem.
