    • 2 mixtures. This kinetic isotope effect is sufficiently small that it has little influence on the rate parameters derived in the current analysis. A more detailed discussion of the kinetic isotope effect and implications concerning C-H activation will be published seperately. (b) This is equivalent to assuming that the secondary kinetic isotope effect (KIE) is negligible, a reasonable assumption given the primary KIE noted above.
