 | Liu, Feng | Determining the adsorptive and catalytic properties of strained metal surfaces using adsorption-induced stress | We demonstrate a model for determining the adsorptive and catalytic properties of strained metal surfaces based on linear elastic theory, using first-principles calculations of CO adsorption on Au and K surfaces and CO dissociation on Ru surface. The model involves a single calculation of the adsorp... | Strained metal surfaces; Adsorption-induced stress; Adsorptive properties; Catalytic properties | 2004 |

 | Armentrout, Peter B. | Mechanism of proton exchange: guided ion beam studies of the reactions, H(H2O)n+ (n=1-4) + D2O and D(D 2O)n+ (n=1-4) + H2O | Reactions of protonated water clusters, H(H2O)n+ (n=1-4) with D2O and their "mirror" reactions, D(D2O)n+ (n=1-4) with H2O, are are studied using guided-ion beam mass spectrometry. Absolute reaction cross sections are determined as a function of collision energy from thermal energy to over 10 eV. | Collision-induced dissociation; Proton exchange; Protonated water clusters; Exothermic reactions; Deuterium oxide | 2004 |

 | Armentrout, Peter B. | Methane activation by nickel cluster cations, Nin+ (n=2-16): reaction mechanisms and thermochemistry of cluster-CHx (x=0-3) complexes | The kinetic energy dependences of the reactions of Nin+ (n=2-16) with CD4 are studied in a guided ion beam tandem mass spectrometer over the energy range of 0-10 eV. The main products are hydride formation NinD1, dehydrogenation to form NinCD2 1 , and double dehydrogenation yielding NinC1. | Nickel ions; Metal clusters; Deuterated methane; Collision-induced dissociation; Endothermic reactions; Bond energies; Dehydrogenation | 2004 |

 | Armentrout, Peter B. | Probes of spin conservation in heavy metal reactions: experimental and theoretical studies of the reactions of Re+ with H2, D2, and HD | A guided ion beam tandem mass spectrometer is used to examine the kinetic energy dependence of reactions of the third-row transition metal cation, Re1, with molecular hydrogen and its isotopologues. A flow tube ion source produces Re1 in its 7S3 electronic ground state. | Endothermic reactions; Transition metal ions; Rhenium ions; Dihydrogen | 2004 |

 | Armentrout, Peter B. | Reaction of Cu+ with dimethoxyethane: competition between association and multiple dissociation channels | The reaction of Cu1 with dimethoxyethane (DXE) is studied using kinetic-energy dependent guided ion beam mass spectrometry. The bimolecular reaction forms an associative Cu1(DXE) complex that is long-lived and dissociates into several competitive channels: C4H9O2 11CuH, Cu1(C3H6O)1CH3OH, back to rea... | Dimethoxyethane; Copper ions; Association reactions; Collision-induced dissociation; Phase state theory | 2004 |
