Abstract : High-resolution spectra of the NO2 continuum emission produced from the reaction NO + O3 to NO2 + O2 have been investigated to detect any possible emission from O2 singlet Delta at 1270 nm or 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 collisions result in production of O2 singlet Delta or Sigma states, respectively, at room temperature.
