An FTIR Study of the Products of the Reaction between CH₂{article}{empty}{document}( X³ B₁){document} and NO

The product channels were investigated of the reaction between CH 2 and NO in the gas phase at room temperature and near ambient pressure. Mixtures of CH 2 CO/NO/Ar were photolyzed at λ = 312 nm in a static reactor. The reaction products were analyzed by Fourier transform infrared (FTIR) spectroscopy. The main product (≈︁ 84%) was found to be fulminic acid, HCNO. A second channel (≈︁ 15%) was found to lead to HCN. Other products which were detected include CO, N 2 O, H 2 O, HONO, H 2 CO, and CO 2 . These are formed (except for the CO from the CH 2 CO photodissociation) in consecutive reactions of the accompanying H atoms and OH radicals from the HCNO and HCN reaction channels.
