Product Channel Dynamics of the NCO + NO Reaction

Article abstract of DOI:10.1021/j100115a033

The NCO + NO reaction was studied by time-resolved infrared diode laser spectroscopy.The CO2 + N2 channel was found to account for 56 +/- 7 percent of the total reaction rate, with N2O + CO accounting for the remaining 44 +/- 7percent.These branching ratios were found to be independent of temperature in the range 296-623 K.Furthermore, the CN + O2 reaction at room temperature produces CO + NO products with a yield of 23 +/- 10percent in addition to the NCO + O channel, with a significant negative temperature dependence.Product energy disposal studies were also performed.CO vibration and the ν₃ mode of CO2 were found to account for only 0.55percent and 3.4percent of the available energy, respectively.These results are discussed in terms of statistical models and simple ab initio computations.
