The temperature dependence of the vibration–vibration energy transfer between the v 3 mode of N 2 O and the first vibrational level of CO was determined over a range of 780 to 1400°K using a shock tube. Several mixtures of CO‐N 2 O were tested, diluted in 95% Ar. The Landau–Teller plot of the vibration–vibration relaxation times has a least squares line of\documentclass{article}\pagestyle{empty}\begin{document}$$ {\rm log}_{{\rm 10}} p\tau _{{\rm VV}} = 2.69T^{ - 1/3} - 1.70 $$\end{document}where pτvv is in atm ˙μsec and T in °K. The measured kinetic reaction was determined to be\documentclass{article}\pagestyle{empty}\begin{document}$$ {\rm N}_{\rm 2} {\rm O(001) + CO(O)} \to {\rm N}_{\rm 2} {\rm O}(000) + {\rm CO(1) + 81cm}^{{\rm - 1}} $$\end{document}The transfer probabilities for this process were found to vary directly with temperature.
