A diode laser study of the product branching ratio of the CH+N2O reaction

The reactions of CH and CD radicals with N2O were studied at room temperature by an excimer photolysis/infrared absorption technique, using multiphoton photolysis of CHBr3 or CDBr3 at 248 nm. Two product channels were detected: HCN+NO in 72±4% yield, and CO+H+N2 in 28±4% yield. No detectable change in the branching ratios upon deuteration was observed.
