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

Contributions of intermolecular electron energy transfers in the electronic quenching are calculated for molecular collisions N2(A6 u , W 1u)+N2(X6 g , v=0), N2(A6 u )+N2(X 16+ g , v≥0), N2(A 36+ u )+O2(X 36− g , v=0– 2), O2(a1g , b16+ g )+O2(X 36− 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(X6 g ) and O2(X6 g ) molecules. In many cases, the calculated rate coefficients have a good agreement with available experimental data.
