The gas phase reactions of CN and NO

Absolute rate constants have been measured for the reactions between CN (v) and NO. Flash photolysis of cyanogen was used to generate CN (v), while laser induced fluorescence was used to monitor this radical. The depletion of CN (v) was considered in terms of the following scheme: The following values were obtained for the rate constants: CN(v=0), k1=1.2±0.6×10−13 cm3 molecule−1⋅s−1; k3=7.7±1.4×10−31 cm6 molecule−2⋅s−1; CN(v=1), (k1+k2) =2.6±0.5×10−13 cm3 molecule−1⋅s−1; k3=3.0±1.1×10−31 cm6 molecule−2⋅S−1.
