Production of NH(ND) radicals in the reactions of N(22D) with H2(D2): Nascent vibrational distributions of NH(X 3Σ−) and ND(X 3Σ−)

A mixture of NO and H2(D2) was irradiated with an intense laser pulse at 275.2 nm which dissociates NO to produce N(2D). Electronically ground state NH(ND) radicals could be detected as products of the N(2D)+H2(D2) reaction by laser-induced fluorescence. The nascent vibrational population ratios, NH(v″=1)/NH(v″=0) and ND(v″=1)/ND(v″=0), were determined to be 0.9 and 1.0, respectively.
