  FTMS Studies of Sputtered Metal Cluster Ions: (II) The Chemistry of Nin+ with C2H4 and CH4 at Long Timescales

  摘要：

  AbstractNickel cluster cations, generated in an external source by sputtering with 20 keV Xe+ were transferred to the ICR cell of a Fourier transform mass spectrometer (FTMS), collisionally cooled, and trapped for long time periods. During storage, the chemistry of Nin+ was studied with ethylene and methane in the range n = 1 … 20. Rather than undergoing adsorption as an intact unit, C2H4 was dehydrogenated in the 1.2‐position to yield HCCH adducts Nin(C2H2)m+ with a dramatic size‐specificity: Whereas Nin+ ions proved absolutely inert for n = 1, 3, 4, they were found highly reactive from n = 5 on. Cyclotroning in the presence of C2H4 for up to 40 s, Ni5+ was found to add on a maximum of nine C2H2 ligands. A second “hidden” size‐specific effect was discovered between n = 11 and n = 12, where dehydrogenation intensifies to yield NinC6+ as final products. These are being discussed in terms of close‐packed lattice structures. Finally, the threshold for methane activation by Ni5+ leading to Ni5C+ was determined to be 2.0 ± 0.5 eV.

  Spectroscopic studies of nickel and iron clusters at 12 K

  摘要：

  The electronic and far-infrared spectra of nickel and iron clusters trapped in argon matrices at 12 K are reported. The ν3 antisymmetric stretching frequencies for Ni3 and Fe3 were observed for the first time at 198 and 180 cm−1, respectively. The fr and frr force constants for Ni3 are calculated to be 0.80 and 0.13 mdyn/Å, respectively. For Fe3 these are 0.67 and 0.13 mdyn/Å.

  atoms or ions produces copious amounts of cluster ions, among which M+(H2O)n and/or M+OH(H2O)n frequently dominate. Variable-energy collision-induced dissociation of these ions in a triple quadrupole mass spectrometer yields the successive gas-phase solvation energies. Several known hydration and bond energies have been reproduced, and the first and second hydration energies of the Cu+ ion have been

  Diatomic nickel–copper, NiCu, has been investigated by resonant two-photon ionization spectroscopy in a jet-cooled molecular beam. Six band systems have been identified over the range 11 500–16 500 cm−1. The ground state of NiCu has been determined to be X 2Δ5/2, with ω″e =273.01±1.15 cm−1, ω″ex″e =1.00±0.38 cm−1, and r″e =2.233±0.006 Å. This state derives from a strongly bound (2.05±0.10 eV) 3d10Cu3d9Ni 4sσ2 configuration. Excited states observed in this work derive from the more weakly bound 3d10Cu3d8Ni 4sσ24sσ*1 configuration, and are characterized by smaller vibrational frequencies (191–208 cm−1) and a longer bond length (2.351±0.005 Å) than the ground X 2Δ5/2 state.

  The kinetic energy dependence of collision-induced dissociation (CID) of Ni2+ and Ni3+ with Xe has been investigated with a guided ion beam mass spectrometer. Interpretation of the CID cross section threshold of Ni2+ allows the binding energy of Ni2+ to be determined as 2.08 +/- 0.07 eV. This value is also confirmed by the CID cross section for Ni3+. This bond energy is well below the range of 3 to 3.5 eV obtained from the photodissociation of Ni2Ar+. The origins of the discrepancy between the two studies are discussed.
