The kinetics of exchange by vibrational quanta is studied theoretically and experimentally in highly excited CO molecules by analysing the recovery time of the inversion population on the selected vibrational-rotational transitions in a doubly Q-switched pulsed CO laser. A model of vibrational kinetics that takes into account the multiquantum vibrational exchange between CO molecules in the temperature range between 100 and 300 K is described in detail for the first time. This model is compared with the model of single-quantum vibrational exchange. Good agreement between experimental data and theoretical calculations performed using the model of multiquantum vibrational exchange is the first direct confirmation of the validity of this model.
