Kinetics of the reactions of NCO radicals with H2 and NO using laser photolysis–laser induced fluorescence

Abstract

Absolute rate constants for the reaction of NCO radicals with hydrogen (k₆; T=592–913K) and nitric oxide (k₇;T=294–538K) were measured using excimer laser photolysis‐laser induced fluorescence at 416.8 nm. The following Arrhenius expressions summarize the data: k₆=1.43×10⁻¹¹e^{(−9000±1500)/RT} k₇=1.69×10⁻¹¹e^{(390±320)/RT} cm³ molecule⁻¹ s⁻¹. The experimental technique and results are discussed, and the importance of these reactions to combustion chemistry is addressed.
