Morley, C

Laser fluorescence was used to detect OH, NH, CN and NO in rich premixed H/sub 2//O/sub 2//Ar flames at 1790-2200 K doped with CH/sub 3/CN. The results are consistent with NO and N/sub 2/ being formed by reactions involving nitrogen atoms. Approximate upper limits on the reactions of NO with NH and NH/sub 2/ are 7*10/sup -12/ and 8*10/sup -12/ cm/sup 3/ molecule/sup -1/ s/sup -1/ at 1790 K. The results do not rule out the possibility that the route through NH/sub 2/ proposed by Fenimore can become significant in flames of low radical concentration. 2 refs.
