The study of intermolecular energy transfers in electronic energy quenching for molecular collisions N2-N2, N2-O 2, O2-O2

Abstract

Contributions of intermolecular electron energy transfers in the electronic quenching are calculated for molecular collisions N2(A 3Σu+, W 3Δu)+N2(X 1Σg+, v=0), N2(A 3Σu+)+N 2(X1Σg+, v≥0), N2(A 3Σu+)+O 2(X3Σg−, v=0–2), O2(a1Δ g, b1Σ g+)+O2(X3& Sigma;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(X1Σg+) and O2(X3Σ g−) molecules. In many cases, the calculated rate coefficients have a good agreement with available experimental data.
