  Neutralized ion‐beam studies of the rare gas hydrides: Observation of unique metastability for NeH

  摘要：

  The rare gas hydride radicals have been produced by charge exchange of the corresponding ion in a mass selected, high velocity beam with K, Na, Mg, Zn, or Hg target metals. NeH shows unique behavior, being produced in both dissociative and long-lived (>5.0 μs) metastable states. Arguments based on energetic considerations are presented that the observed metastability should be associated with the ground state of the NeH radical, requiring that it have a shallow well and dissociation barrier analogous to those previously determined for the ground states of the isoelectronic NH4, H3O, and H2F radicals. The existence of a structured radiative transition near 6.1 eV is predicted for the NeH radical. The other rare gas hydrides exhibit only dissociation of the radical with the kinetic energy released explainable in terms of production of known electronic states of the radicals by near resonant electron transfer. For HeH and ArH the first excited electronic state (A 2Σ+) is observed to efficiently predissociate into the repulsive ground state, whereas for KrH and XeH, lower limits of 4.5 and 3.9 eV, respectively, are determined for the energies of the corresponding excited states with respect to the separated ground state atoms.

  Molecular Ions Formed by Field Ionization

  摘要：

  AbstractThe formation of ions in high electric fields in front of field emitters is investigated by mass spectrometry and appearance spectroscopy. The combination of these methods provides information on ion generating processes and molecular properties in high electric fields. For noble gases ionization potentials are determined, for hydrogen (H+, H2+, H3+) detailed information is given for ionization, field‐induced dissociation, and surface interaction (H3+). Protonated rare gas molecular ions are formed by a fast adiabatic proton stripping, without reflecting values of proton affinities in appearance energies. Field‐induced surface reactions form sulfur chains (Sx, x ≦ 22) from S2 molecules, while ring structures (Sx, with x = 8 most abundant) predominate when field pulse desorption with zero reaction field is applied. Cluster‐ions with low internal binding energy (like (H2O)n · H+, n ≦ 12) are formed at low temperatures and by using photon‐induced field desorption.

• Rovibrational intensities for the fundamental band ν = 1—0 of ArH+

  Relative line intensities have been measured by Fourier-transform infrared emission spectroscopy of the 1—0 vibration—rotation band of ArH+. The ratio of the dipole moment to the dipole derivative has been determined independently of knowing the ion concentration from the variation of intensity with rotation. The result is in agreement with ab initio theoretical studies of the electric-dipole-moment

  相对线强度已经通过ArH +的1-0振动-旋转带的傅里叶变换红外发射光谱法进行了测量。已经确定了偶极矩与偶极导数之比，而与从强度随旋转的变化中知道离子浓度无关。该结果与电偶极矩函数的从头算理论研究相一致。

  The proton transfer reactions from ArH+ to H2, D2, CH4, N2, O2, CO, CO2, and the corresponding deuteron transfer reaction of ArD+ with H2 and D2 have been investigated in a drift tube with mass selected ion injection. The use of helium and argon buffer gases permits a qualitative assessment of vibrational energy effects along with a quantitative assessment of the influence of translational energy on reaction rates. These exothermic reactions all proceed with large rate coefficients which approach the collision rates for the respective reactants. All except the reaction of ArH+ with H2 (D2) were independent of translational energy over the range investigated. In an argon buffer equilibrium is readily established for the reaction ArH++H2⇄H3++Ar. A treatment of the center-of-mass kinetic energy as a ’’translational temperature’’ permits the construction of a van’t Hoff plot for this reaction from which a value of Δ(PA)=0.55 eV is obtained, which is consistent with the accepted proton affinities of H2 and Ar.
