在氩气中稀释的氰化物和氧化亚氮的混合物，用激波加热的方法测量了反应的速率常数
Mixtures of cyanogen and nitrous oxide diluted in argon were shock-heated to measure the rate constants of
A broad-band mercury lamp was used to measure CN in absorption at 388 nm [B2Σ+(v = 0) X2Σ+(v = 0)], and the spectral coincidence of a CO infrared absorption line [v(2 1), J(37 38)] with a CO laser line [v(6 5), J(15 16)] was exploited to monitor CO in absorption. The CO measurement established that reaction (3) produces CO in excited vibrational states. A computer fit of the experiments near 2000 K led to
An additional measurement of NO via infrared absorption led to an estimate of the ratio k5/k6:
with k5/k6 ≃ 103.36±0.27 at 2150 K. Mixtures of cyanogen and oxygen diluted in argon were shock heated to measure the rate constant of
and the ratio k5/k6 by monitoring CN in absorption. We found near 2400 K:
and
The combined measurements of k5/k6 lead to k5/k6 ≃ 10−3.07 exp(+31,800/T) (±60%) for 2150 ≤ T ≤ 2400 K.
