## 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 An approximate analytical solution of relaxation in a low‐pressure system with exponential transition probabilities is given for vibrational–rotational energy transfer in the dissociation of diatomics. The main assumption is that the rotational degrees of freedom are in thermal equilibr
