 | Armentrout, Peter B. | Activation of methane by size-elected iron cluster cations, Fen+ (n=2-15): cluster-CHx (x=0-3) bond energies and reaction mechanisms | The kinetic energy dependences of the reactions of Fen + (n=2 - 15) with CD4 are studied in a guided ion beam tandem mass spectrometer over the energy range of 0-10 eV. All reactions exhibit thresholds and two main products, FenD+ and FenCD2+, are formed. | Metal clusters; Iron ions; Bond energies; Dehydrogenation; Endothermic reactions; Transition metal ions | 2001 |

 | Armentrout, Peter B. | Collision-induced dissociation processes of Nb4+ and Fe4+: fission vs. evaporation | Despite the extensive effort devoted to research on gasphase metal clusters, quantitative thermodynamic data on such species are scarce. Such information is key to understanding and predicting the physical and chemical properties of clusters. Presently, bond energies are available primarily for tr... | Metal clusters; Nobium ions; Iron ions; Fission; Evaporation | 1988 |

 | Armentrout, Peter B. | Oxidation reactions at variably sized transition metal centers: Fen+ and Nbn+ + O2 (N=1-3) | Cross sections for the reactions of Fen+ and Nbn+ (n = 1-3) with 02 are measured as a function of kinetic energy over a range of 0 to > 10 eV. In all systems, analysis yields insight into the kinetics and thermochemistry of the oxidation processes. Nbn+ reaction with 02 exothermically near the Lange... | Metal clusters; Nobium ions; Iron ions; Exothermic reactions | 1989 |

 | Armentrout, Peter B. | Thermochemistry of the activation of N2 on iron cluster cations: guided ion beam studies of the reactions of Fen+ (n=1-19) with N2 | The kinetic energy dependences of the reactions of Fen + (n=1-19) with N2 are studied in a guided ion beam tandem mass spectrometer over the energy range of 0-15 eV. In addition to collision-induced dissociation forming Fem + ions, which dominate the product spectra, a variety of FemN2+ and FemN+ p... | Metal clusters; Iron ions; Dinitrogen; Endothermic reactions; Collision-induced dissociation; Bond energies | 2006 |
