A summary of 3 values

It is informative to list and compare the f3 values for the distance dependence of superexchange-mediated ET rates through the various types of bridges reviewed in this article. For consistency, the units of (3 are given in A-1. 

From the data given in equations (24)-(28), we may conclude that super-exchange-mediated ET through the DNA duplex is significant and that (3 for DNA may be comparable to the upper limit of j3 observed for conjugated hydrocarbon bridges. However, it now seems clear that DNA does not behave as a molecular wire in ET reactions, as has been posited.178
