1 Morse, Michael David???X??+ band systems of jet-cooled ScCo and YCoRotationally resolved resonant two-photon ionization (R2PI) spectra of ScCo and YCo are reported. The measured spectra reveal that these molecules possess ground electronic states of 1?+ symmetry, as previously found in the isoelectronic Cr2 and CrMo molecules. The ground state rotational constant...2010
2 Wight, Charles Albert; Anderson, Richard BryanElectronic publication of theses and dissertationsFor many years, the university has required its doctoral students to print and publish their dissertations. After a dissertation has been approved for release by the Graduate School thesis editors and the student has been approved for graduation, the university sends one copy of the manuscript to Pr...Electronic publication; Theses; Dissertations2010
3 Morse, Michael DavidElectronic spectroscopy and electronic structure of diatomic CrCOptical spectra of jet-cooled diatomic CrC have been recorded in the near infrared region using resonant two-photon ionization spectroscopy combined with mass-selective detection of the resulting ions. Several weak transitions have been observed, along with one relatively strong band near 842 nm. Ro...2010
4 Armentrout, Peter B.Guided ion beam and theoretical studies of the reaction of Ag+ with CS2: gas-phase thermochemistry of AgS+ and AgCS+ and insight into spin-forbidden reactionsThe gas-phase reactivity of the atomic transition metal cation, Ag+, with CS2 is investigated using guided-ion beam mass spectrometry. Endothermic reactions forming AgS+ and AgCS+ are observed but are quite inefficient. This observation is largely attributed to the stability of the closed shell Ag+(...2010
5 Armentrout, Peter B.Guided ion beam and theoretical studies of the reaction of Ru+ with CS2 in the gas-phase: thermochemistry of RuC+, RuS+, and RuCS+Abstract: The gas-phase reactivity of the atomic transition metal cation, Ru+, with CS2 is investigated using guided-ion beam mass spectrometry (GIBMS). Endothermic reactions forming RuC+, RuS+, and RuCS+ are observed. Analysis of the kinetic energy dependence of the cross sections for formation of ...2010
6 Armentrout, Peter B.Infrared multiple photon dissociation spectroscopy of cationized cysteine: effects of metal cation size on gas-phase conformationAbstract The gas-phase structures of cationized cysteine (Cys) including complexes with Li+, Na+, K+, Rb+, and Cs+, as well as protonated Cys, are examined by infrared multiple photon dissociation (IRMPD) action spectroscopy utilizing light generated by a free electron laser, in conjunction with q...2010
7 Armentrout, Peter B.Infrared multiple photon dissociation spectroscopy of cationized methionine: effects of alkali-metal cation size on gas-phase conformationPlease note that as of 11-07-2012, access to this article through USpace had to be restricted. The gas-phase structures of alkali-metal cation complexes of the amino acid methionine (Met) as well as protonated methionine are investigated using infrared multiple photon dissociation (IRMPD) spectros...2010
8 Miller, Joel StevenMnII(TCNE)3/2(I3)1/2-A 3D network-structured organic-based magnet and comparison to a 2-D analogOrganic-based magnets utilize unpaired electrons residing on organic species to form magnetically ordered materials. Unlike traditional atom/ion-based magnets, they enable the controllable modulation and combination of magnetic properties with other technologically important properties (e.g., electr...2010
9 Voth, Gregory AlanThe multiscale coarse-graining method. VI. Implementation of three-body coarse-grained potentialsMany methodologies have been proposed to build reliable and computationally fast coarse-grained potentials. Typically, these force fields rely on the assumption that the relevant properties of the system under examination can be reproduced using a pairwise decomposition of the effective coarse-grai...2010
10 Voth, Gregory AlanQuantitative assessment of the accuracy of centroid molecular dynamics for the calculation of the infrared spectrum of liquid waterA detailed analysis of the infrared lineshapes corresponding to the intramolecular bond vibrations of HOD in either H2O or D2O is presented here in order to quantitatively assess the accuracy of centroid molecular dynamics in reproducing the correct features of the infrared spectrum of water at amb...2010
11 Armentrout, Peter B.Relative and absolute bond dissociation energies of sodium cation-alcohol complexes determined using competitive collision-induced dissociation experimentsAbsolute (R1OH)Na+-(R2OH) and relative Na+-(ROH) bond dissociation energies are determined experimentally by competitive collision-induced dissociation of (R1OH)Na+(R2OH) complexes with xenon in a guided ion beam mass spectrometer. The alcohols examined include ethanol, 1-propanol, 2-propanol, n-but...2010
12 Morse, Michael DavidResonant two-photon ionization spectroscopy of jet-cooled tantalum carbide, TaCThe optical spectrum of diatomic TaC has been investigated for the first time, with transitions recorded in the range from 17 850 to 20 000 cm?1. Six bands were rotationally resolved and analyzed to obtain ground and excited state parameters, including band origins, upper and lower state rotational...2010
13 Stang, Peter J.Self-assembly of coordinative supramolecular polygons with open binding sitesThe design and synthesis of coordinative supramolecular polygons with open binding sites is described. Coordination-driven self-assembly of 2,6-bis(pyridin-4-ylethynyl)pyridine with 60? and 120? organoplatinum acceptors results in quantitative formation of a supramolecular rhomboid and hexagon, resp...2010
