摘要：

Absolute rate coefficients for the reaction NH2 + NO were measured by time resolved observation of the OH radical formation at temperatures 294 - 1025 K in a heatable quartz reactor by means of the laser photolysis/laser induced fluorescence technique. The data can be represented by the expression: k1 = (7.9 +/- 1.0) . 10(15) T-(1.17 +/- 0.25) cm3/mol s. The branching ratio beta into the OH product channel was determined to be 0.1 +/- 0.025 at 300 K; beta increases with increasing temperature and reaches a value of 0.19 +/- 0.05 at 1000 K.
