The calculation of quenching rate coefficients of O_2 Herzberg states in collisions with CO_2, CO, N_2, O_2 molecules

摘要

The removal rates of Herzberg states of molecular oxygen O_2(c~1∑_u~-, v = 0-16), O_2(A~(03)Δ_u, v = 0-11), O_2(A~3∑_u~+, v = 0-10) in the collisions with ground-state CO_2, CO, N_2, O_2 molecules are calculated according to analytical expressions. The study includes a consideration of intramolecular electron energy transfers without and with vibrational excitation of target molecules and intermolecular processes. The preliminary calculations show important role of electronic-vibrational energy transfer processes in the quenching O_2(A~3∑_u~+, v) + CO_2; O_2(c~1∑_u~-, v) + CO_2, CO, N_2; O_2(A~(03)Δ_u, v) + O_2. Reasonable agreement of the calculated rate coefficients with data of laser experimental measurements is obtained.
