Rate constant for the reaction of N(4S) with CH3 AT 298 K

Abstract The absolute rate constant for the reaction of N( 4 S) with CH 3 has been determined at 298 K in a discharge flow system coupled with collision-free sampling mass spectrometry at low electron energies. The rate constant was determined under pseudo-first-order conditions with [N] > [CH 3 ]. The result is k 1 = (8.6±2.0) × 10 −11 cm 3 s −1 . This is compared to a previous estimated value as well as values of rate constants for other atom + radical reactions.
