Kinetic studies of elementary reactions using the flash photolysis-shock tube technique

The development of the flash photolysis-shock tube technique is reviewed and the advantages and limitations of the method are discussed. Kinetic obtained with the Brookhaven FP-ST facility over the 800K to 2500K temperature range, are described for the following atom-molecule reactions: (1) H + NH/sub 3/ ..-->.. NH/sub 2/ + H/sub 2/; (2) O + CH/sub 4/ ..-->.. OH + CH/sub 3/; (3) O + H/sub 2/ ..-->.. OH + H; (4) H + H/sub 2/O ..-->.. OH + H/sub 2/; (5) H + O/sub 2/ ..-->.. OH + O; (6) H + O/sub 2/ + M ..-->.. HO/sub 2/ + M; (7) O + C/sub 2/H/sub 4/ ..-->.. Products. The results obtained in this laboratory for reactions (1), (2), (3) and (7) are compared with those reported previously. 26 refs., 6 figs.
