coefficients for the reactions of CN(ν=1, 0) radicals with O2 (k1) and H2 (k2) were measured from 294 to 1000 K in a heatable quartz reactor by means of a laser photolysis/laser-induced fluorescence technique. The data fit the expressions k1 (T) (CN(ν=0)) = (8.7±1.0) × 1012 exp[ + (1.8±0.4) kJ/RT] cm3 mol−1 s−1, k1 (T) (CN(ν=1)) = (8.4±1.2) × 1012 exp [+(1.2± 0.4) kJ/RT] cm3 mol−1 s−1 and k2 (T) (CN(ν=0)) = (3
在可加热的石英反应器中,通过激光光解/激光,测量了CN(ν= 1,0)自由基与O 2(k 1)和H 2(k 2)反应的绝对速率系数,从294到1000 K诱导的荧光技术。数据符合表达式k 1(T)(CN(ν= 0)) =(8.7±1.0)×10 12 exp [+(1.8±0.4)kJ / RT ] cm 3 mol -1 s -1,k1(T)(CN(ν= 1)) =(8.4±1.2)×10 12 exp [+(1.2±0.4)kJ /RT ] cm 3 mol -1 s -1和k 2(T)(CN(ν= 0)) =(3.1±0.3)×10 5 T 2.45 exp [-(9.3±0.2)kJ / RT ] cm 3 mol -1 s -1。
