The study of intermolecular energy transfers in electronic energy quenching for molecular collisions N₂-N₂, N₂-O₂, O₂-O₂

Abstract. Contributions of intermolecular electron energy transfers in the electronic quenching are calculated for molecular collisions N₂(A³Σ_u⁺, W³Δ_u)+N₂(X¹Σ_g⁺, v=0), N₂(A³Σ_u⁺)+N₂(X¹Σ_g⁺, v≥0), N₂(A³Σ_u⁺)+O₂(X³Σ_g⁻, v=0–2), O₂(a¹Δ_g, b¹Σ_g⁺)+O₂(X³Σ_g⁻, v=0–2). The calculation has allowed one to estimate the product branching ratios. It is shown that there is a dependence of the calculated rate coefficients on the vibrational excitation of N₂(X¹Σ_g⁺) and O₂(X³Σ_g⁻) molecules. In many cases, the calculated rate coefficients have a good agreement with available experimental data.
