The calculations of quenching rate coefficients of O2(b1g+, v) in collisions with O2, N2, CO, CO2 molecules

Abstract

The removal rates of singlet molecular oxygen O2(b1Σg+,v=0–15) in the collisions with O2(X3Σg−,v=0–4), N2(X1Σg+,v=0–4), CO(X1Σ+,v=0–4) molecules are calculated according to analytical expression based on Rosen–Zener approximation. The calculations consider electronic-vibrational energy transfer processes in the removal. The study of the quenching of O2(b1Σg+,v) molecules by CO2 includes a consideration of both electronic-vibrational and vibrational–vibrational energy transfer processes. The calculated quenching rate coefficients for the collisions O2(b1Σg+,v)+CO2 show good agreement with available experimental data in the dependence on vibrational levels and temperature.
