Abstract

The rate coefficients of the reactions of CN and NCO radicals with O2 and NO2 at 296 K: (1) CN + O2 → products; (2) CN + NO2 → products; (3) NCO + O2 → products and (4) NCO + NO2 → products have been measured with the laser photolysis‐laser induced fluorescence technique. We obtained k1 = (2.1 ± 0.3) × 10−11 and k2 = (7.2 ± 1.0) × 10−11 cm3 molecule−t s−1 which agree well with published results. As no reaction was observed between NCO and O2 at 297 K, an upper limit of k3 < 4 × 10−17 cm3 molecule−1 S−1 was estimated. The reaction of NCO with NO2 has not been investigated previously. We measured k4 = (2.2 ± 0.3) × 10−11 cm3 molecule−1 s−1 at 296 K.
