Influence of resonance excitation of rotational levels on the energy balance in the plasma of gas discharges in N2, CO, CO2, and He mixtures

An analysis is made of the influence of resonance excitation of the rotational levels of the nitrogen molecule on the energy balance in electrical discharges in nitrogen-rich CO, CO₂, and He mixtures. An analysis is made of the influence of the excitation of the rotational degrees of freedom of nitrogen on the parameters of amplification in a CO₂–M₂–He plasma. It is shown that the resonance excitation of the rotational levels of nitrogen has to be allowed for in the case of discharges in nitrogen-rich mixtures characterized by a low value of the ratio E/N ≤ 1×10^–16V·cm².
