Abstract
The electronic‐energy pooling reactions forming O2(1Σ) are of critical importance to the overall mechanism of the O2(1Δ)–I atom transfer laser. In this study, we report temperature‐dependent rate coefficient data for O2(1Δ)+O2(1Δ)→k2O2(1Σ)+O2(3Σ) and O2(1Δ)+I(2P1/2)→k3O2(1Σ)+I. These data were obtained using a temperature‐controlled kinetic flow tube equipped with computer‐controlled spectroscopic diagnostics. The fundamental data reported are k2(T)/k2(295) = (3.5±1.5)exp(−780/RT) and k3(T)/k2(T) = (5.5±1.0)×103. Both rate‐coefficient ratios are reported for the temperature range T = 259 to 353 K. The results are compared with earlier measurements of these processes.Keywords
