The temperature dependence of the vibration–vibration energy transfer between the v 3 mode of 15 N 14 NO and the first vibrational level of CO was determined over a range of 680 to 1300°K using a shock tube. Several mixtures of 15 N 14 NOCO were tested, diluted in 95% Ar. The resulting exothermic transfer probabilities for the reaction,\documentclass{article}\pagestyle{empty}\begin{document}$$ ^{15} {\rm N}^{14} {\rm NO}(001) + {\rm CO}({\rm O}) \to ^{15} {\rm N}^{14} {\rm NO}(000) + {\rm CO}(1) $$\end{document} are compared to previous work on N 2 O—CO. The results for 15 N 14 NOCO exhibit a more pronounced direct temperature dependence than for N 2 O—CO even though the process has a closer resonance (Δ E = 59 cm −1 for 15 N 14 NOCO and Δ E = 81 cm −1 for N 2 OCO).
