  • Quantitative determination of emerging contaminants, solvent stabilizers and fullerene nanomaterials, in biological and environmental systems

    Creator:
    Isaacson, Carl W.
    Abstract:
    To determine the impact of emerging environmental contaminants on human and environmental health, quantitative analytical methods are required. Analysis of emerging contaminants is hampered by their widely varying physical-chemical properties. Therefore quantitative analytical methods must be developed to determine the behavior of emerging contaminants in environmental systems. A quantitative analytical...

  • High resolution spectroscopic studies of ³²S¹⁶O₃ and ³⁴S¹⁶O₃

    Creator:
    Barber, Jeffrey
    Abstract:
    The two sulfur isotopomers of sulfur trioxide, ³²S¹⁶O₃ and ³⁴S¹⁶O₃, have been studied via high resolution infrared and Coherent anti-Stokes Raman (CARS) spectroscopy. The v₁ symmetric SO stretching Q-branches observed by the latter are quite different, being especially complex for ³²S¹⁶O₃ Understanding this band structure required analysis of infrared-active hot...

  • Computational Rationalizations of Mechanism and Stereocontrol in Small-Molecule Lewis Base Organocatalysis

    Creator:
    McCauley-Walden, Daniel W.
    Abstract:
    My work has focused on investigating synthetic organic reactions using applied computational methods. Non-covalent interactions are critical to catalysis, mechanism, and stereoselectivity, with the most prominent interaction for isothioureas being the S···O contact between the catalyst sulfur atom and the oxygen of the acyl group. A comprehensive joint experimental and...

  • The Total Kinetic Energy Release in the Fast Neutron-induced Fission of ²³²Th

    Creator:
    King, Jonathan W.
    Abstract:
    The post-emission total kinetic energy release (TKE) in the neutron induced fission of ²³²Th was measured (using white spectrum neutrons from LANSCE) for neutron energies from En = 3 to 91 MeV. In this energy range the average post-neutron total kinetic energy release decreases from 162.3 ± 0.3 at En...

  • A Diels-Alder approach to biaryl synthesis

    Creator:
    Ashburn, Bradley O.
    Abstract:
    An expedient approach to the synthesis of a wide range of highly programmable biaryl templates has been accomplished. Utilizing the Diels-Alder [4+2] cycloaddition, a wide range of tri- and tetra-ortho-substituted biaryls have been synthesized in only three to four steps from commercially available materials. We have successfully synthesized entire classes...

  • High resolution spectroscopy of sulfur trioxide and carbon suboxide

    Creator:
    Masiello, Tony
    Abstract:
    High resolution spectroscopy was used to study the properties of two simple polyatomic molecules, sulfur trioxide, SO₃, and carbon suboxide, C₃O₂. The fundamental modes and several hot bands of the ¹⁸O isotopic fonns of SO₃ (³²S¹⁸O₃ and ³⁴S¹⁸O₃) have been investigated using both infrared spectroscopy and coherent anti-Stokes Raman scattering...

  • Deposition and characterization of transition metal oxides from aqueous solution

    Creator:
    Betterton, Sharon A.
    Abstract:
    The aqueous chemistries of two transition metal cations, Zr⁴⁺ and Nb⁵⁺, are examined and then used to develop inorganic precursor solutions. The oxides of these cations (ZrO₂ and Nb₂O₅) are deposited and characterized, and their morphological and optical properties discussed. Due to the obstacles created by niobium's aqueous chemistry, an...

  • Synthesis and structure of new transition metal containing bismuth oxides

    Creator:
    Xun, Xiumei
    Abstract:
    Exploratory synthesis is the discovery of new compounds with interesting structures and properties. The subject of this thesis is exploratory synthesis of bismuth containing oxides. Bismuth containing oxides have many interesting properties, which are ionic conductivity, ferromagnetism, superconductivity, ferroelectricity, ferroelasticity and catalytic. These properties are closely related to their specific...

  • High resolution ionization-detected simulated Raman spectroscopy

    Creator:
    Crew, Marshall D.
    Abstract:
    A new experimental apparatus was built at Oregon State University to perform high resolution stimulated Raman spectroscopy in a pulsed molecular jet at state densities of the order of 10¹¹ cm⁻³. The technique uses a stimulated Raman step to first populate a vibrational/rotational level and then a resonantly enhanced multiphoton...

  • Applications of nonlinear raman spectroscopy

    Creator:
    Melin, Stéphanie
    Abstract:
    Two nonlinear optical experiments are presented in which the third-order electronic susceptibility of molecules is used to generate Raman signals. The first one uses a single 532 nm beam from a Nd:YAG laser to produce Stimulated Raman Scattering in benzene and deuterated benzene. With a simple experimental set-up, stimulated emission...
