Temperature Dependent Quenching Rate Constants of NF(a~1Δ)

摘要

The temperature dependence of the rate constants for NF(a~1Δ) quenching by CI_2, HCI, O_2 and CO over the temperature range 300 - 480 K have been measured in a flow reactor. The rate constant data were fit by Arrhenius expressions k(T, Cl_2) = 1.6 +- 1.0 X 10~(-11) exp(-1100 +- 250 / T), k(T, HCI) = 2.0 +- 1.0 X 10~(-10) exp(-3270 +- 250 / T), k(T, O_2) = 1.5 +- 0.5 X 10~(-14) exp(-300 +- 150 / T) and k(T, CO) = 2.0 +- 1.0 X 10~(-12) exp(-2000 +- 250/T), cm~3 molecules~(-1) s~(-1). Reaction mechanisms and possible products are discussed for each reaction.
