Abstract:
The reaction of hydrogen atoms with NF2 was studied in a flow tube using pulsed KrF laser initiation of H2/NF2/Ar mixtures at 440 K. The quantum yield for NF(a) production from the 249 nm photolysis of NF2 was determined to be 0.10 + or - 0.05. Several important reactions in this system were investigated, and rate coefficients were determined at 440 K. A value of (1.03 + or - 0.20) x 10 to the -30th power cm to the 6th power/sq. molecule -sec was obtained for the three-body recombination of F atoms with NF2 and Ar. Rate constants for the relaxation of HF(v = 2) and HF(v = 3) by NF2 are (9.7 + or - 1.0) x 10 to the -14th power and (2.5 + or - 0.5) x 10 to the -13th power cc/ molecule-sec, respectively. Study of the quenching of NF(a) by NF2 yields a rate coefficient of (2.7 + or -1.0) x 10 to the -16th power cc/molecule-sec. Evidence is presented that indicates the disproportionation of NF(a) is three orders of magnitude slower than that of ground state NF. Modeling results are presented which agree well with experimental data.
