AN FTIR STUDY OF THE PRODUCTS OF THE REACTION BETWEEN CH2((X)OVER-TILDE(3)B(1)) AND NO

The product channels were investigated of the reaction between CH2((X) over bar(3) B-1) and NO in the gas phase at room temperature and near ambient pressure. Mixtures of CH2CO/NO/Ar were photolyzed at lambda = 312 nn in a static reactor. The reaction products were analyzed by Fo urier transform infrared (FTIR) spectroscopy. The main product (approx imate to 84%) was found to be fulminic acid, HCNO. A second channel (a pproximate to 15%) was found to lead to HCN. Other products which were detected include CO, N2O, H2O, HONO, H2CO, and CO2. These are formed (except for the CO from the CH2CO photodissociation) in consecutive re actions of the accompanying H atoms and OH radicals from the HCNO and HCN reaction channels.
