| Abstract: | High-resolution spectra of the NO2 continuum emission produced from the reaction NO + O3 → NO2 + O2 have been investigated to detect any possible emission from O2(1Δg) at 1270 nm or O2(1Σ+g) at 762 nm. The photolysis of O3/O2 mixtures at 253.7 nm, which produces both states of O2 with known quantum efficiency, has been used as an internal standard. From the results it is concluded that less than 1/300 and 1/200 of the NO + O3 reactive collissions result in production of O2(1Δg) or O2(1Σ+g), respectively, at room temperature. |
