Vibrationally Excited Ozone in Kinetics of O/N/Ar Mixtures after Ozone Photolysis

Abstract

The developed kinetics of the vibrationally excited states of ozone (with excitation of up to five vibrational quanta), built into the chemical kinetics of O/N/Ar mixtures, was used to model the series of photolysis experiments of V.N. Azyazov et al. The experimental and calculated dynamics of O3 and O2(a1∆) in various O3/O2/Ar mixtures were compared. The dynamics of chemiluminescent radiation of NO∗2NO2∗ in the titration technique and the applicability of this technique to measuring the dynamics of O atoms in an O3/O2/N2O/Ar mixture were considered. The dynamics of various states of O3(v1,v2,v3) after ozone photolysis was analyzed in detail. The role of these states in the acceleration of the chemical conversion of oxygen components and nitrogen oxides, occurring with competition with ozone vibrational relaxation, was considered.
