## Abstract 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

## Abstract The present study reports the measurement of the V–V energy transfer rates for the CO\*COS system in the temperature range of 195 to 370°K. The measured rates exhibit a slight inverse temperature dependence. The experimental results are compared to prediction based on a model of long‐r
