    • In the hydroxylation of C-H bonds by P450, the computed KIEs are small for weak bonds with small barriers and larger for stronger bonds and larger barriers. See, for example, C. Li, W. Wu, D. Kumar, S. Shaik, J. Am. Chem. Soc. 2006, 128, 394. Of course, based on the Westheimer-Melander hypothesis, if the free energy of the reaction and the barrier both increase in the same direction for a series of alkanes with a given oxidant, the semiclassical KIE will remain approximately constant
