  Vibrationally state‐selected reactions of ammonia ions. I. NH⁺₃(v)+D₂

  摘要：

  Resonance enhanced multiphoton ionization has been applied to the production of vibrationally state-selected ion beams. Ammonia ions are selectively formed with a specific number of vibrational quanta in the ν2 umbrella bending mode. The effect of vibrational excitation of this mode on the reaction of NH+3(X̃, v=0 to 9) with D2 is examined over the 0.5 to 10 eV center-of-mass kinetic energy range in a tandem quadrupole mass spectrometer. Under these conditions, (1) abstraction of a D atom to form NH3D+ is the dominant reaction channel, (2) NH3D+ having sufficient internal energy may decompose to yield NH2D+ and this decomposition process is enhanced by vibrational excitation of the NH+3 reagent, and (3) NH2D+ is also formed by direct hydrogen–deuterium exchange of NH+3 with D2, but this channel appears as a minor contribution which is insensitive to the vibrational excitation of the NH+3. A spectator stripping model is able to account for the ratio of NH2D+ to NH3D+ as a function of the NH+3 translational and vibrational energy.

  The reactions of N+(3P) ions with normal, para, and deuterated hydrogens have been examined at temperatures below 163 K by using the CRESU technique with both helium and nitrogen buffer gases. All these reactions have decreasing rate coefficients with decreasing temperature. Comparison of the data for normal and para-H2 reveals the drastic importance of rotational energy in promoting these processes. Analysis of these results shows a better agreement between the n-H2, p-H2, and HD data if the spin–orbit energy of N+(3P) is also considered as efficient as kinetic and rotational energies in driving the reactions. It follows that the endothermicity of the reaction N+(3P0) +H2(X 1Σ+g,J=0) →NH+(X 2Π,J=0) +H(2S) is (18±2) meV. This yields a proton affinity of N equal to (3.524±0.003) eV and a dissociation energy of NH of (3.42±0.01) eV.
