Popis: The primary and secondary reactions in the H+NFCl 2 system have been studied by infrared chemiluminescence in a fast flow reactor at 300 K. The primary reaction is exclusively Cl atom abstraction to give HCl(υ=0-4) +NFCl with a total rate constant of (1.9±0.4)×10 -11 cm 3 molecule -1 s -1 and an inverted vibrational distribution of P 0 -P 4 =9:20:32:27:12. The rate constant for HF formation from H+NFCl was estimated as (0.9±0.4)×10 -11 cm 3 molecule -1 s -1 , and the HF vibrational distribution, P 0 -P 3 =42:34:18:6, is characteristics of unimolecular HF elimination reactions. These data for the HF+NCl(a) product channel from the H+ NFCl reaction are compared to earlier studies, which provided information about the HCl+NF(a) product channel
