“…Then, with the improved k7, the process can be repeated until successive iterations give no significant change in k7. The linearity of the plot according to (19), shown in Figure 7b, attests to the validity and internal consistency of the method. The average value obtained from two replicate experiments at 56°is k7 -9.7 ± 0.7 X 10™14 cm3 molecule™1 sec™1.…”

1335were the dominant mechanism.23 This prediction is related to the observation reported in the single-pulse shock tube study of the Hz + Dz exchange that the rate depended more strongly on the concentration of Dz than on H2.21,24 In the temperature range 1050-1200"K, the rate of Dz with CzNz was found to be faster than that of HZ with CzN2 although the rate decreased with increasing tempera t~r e .~~ According to VEC, the important species is CzNz" and not H2U or D2U. Consequently, there should be a decrease in the rate constant as expected from the normal isotope effect when D:l rather than Hz is reacting with CzN2. The magnitude of the isotope effect, A D J A H~, calculated from collision theory, is listed below for both atomic and VEC mechanisms.

The products of the photolysis are nitrogen, hexafluoroethane, perfluorotetramethylhydrazine, and perfluorohexamethyl-and near-ultraviolet regions of the spectrum has been well studiedz-? and often used8-12 as a convenient source of tri-
