Abstract : The existence of large normal secondary kinetic isotope effects in non-equilibrium systems produced by non-thermal methods of activation is discussed. This effect is illustrated in the production of chemically activated ethyl-d sub x radicals. The observed limiting average values for this system at 195 and 300 K and extrapolated to zero pressure were 1.9. A recent summary of secondary isotope effects for equilibrium thermal unimolecular systems gives an average value of 1.12/D atom (S. Seltzer. J. Am. Chem. Soc., 83:2625; 1961).
