Numerical analysis of the vibrational kinetics of СО$_2$ coupled modes

Calculations are performed of the dynamics of formation and the type of quasi-stationary distributions (QD) of vibrational populations of levels of coupled modes in imbalanced carbon dioxide. In typical conditions the establishment of QD occurs over a time which corresponds to $\sim 10^{2}$ of the gas kinetic collisions. The qualitative differences in the acquired QD from Treanor distribution are revealed.
