Reaction:   NO2 + C2OCO2 + NCO
Reaction order:   2
Temperature:   298 K

Comments:   Did not specifically identify products. However, this is likely most favored product channel being 586 kJ/mol exothermic. Other product channels could included CN + CO + O2 endothermic by +5 kJ/mol, and NCCO + O2 product channel.

Measurement of reaction of NO and NO2 with CCO radicals. Also did ab initio calculations at QCISD(T)/6-311G(2df,2pd) level to elucidate pathways. CCO produced by 266 nm photolysis of C3O2. Various reactants and products CCO, CN, N2O, CO, CO2 were detected uisng IR diode laser absorption. Typical total pressure was 1.0 torr SF6 and 1.0 torr Xe with partial pressures of NO and NO2 0.050-0.8 torr and about 0.1-0.5 torr C3O2 as precursor for CCO.
