  • Gas phase x-ray photoelectron spectroscopy of some ketone compounds

    Creator:
    Situmeang, Rudy T. M.
    Abstract:
    The photoelectron spectra of a series of ketone compounds have been investigated in the gas phase. Core ionization energies were measured to probe the effects of molecular size and connectivity number on core ionization energies. It was found that core ionization energies roughly decrease with increasing connectivity number as expected....

  • High-resolution X-ray photoelectron spectroscopy of CO₂ and other small molecules

    Creator:
    Hahne, Jeffrey A.
    Abstract:
    The carbon is photoelectron spectrum of CO₂ has been measured with very high photon energy resolution. The natural lifetime of the carbon is hole state has been determined from a series of spectra taken at photon energies of 308, 320, and 330 eV. The measured values of the lifetimes show...

  • Gas phase x-ray photoelectron spectroscopy of compounds containing multiply-bonded oxygen

    Creator:
    Smith, Steven Reid
    Abstract:
    A new x-ray source capable of operating at up to 80 watts has been designed and developed, and put to use with the Oregon State University Cylindrical Electrostatic Analyzer. The new source produces over four times the photoelectron intensity of its predecessor, from gaseous samples, and accommodates a wider selection...

  • X-ray photoelectron spectroscopy of trifluoromethylbenzenes and chlorofluoromethanes

    Creator:
    Holmes, Steven Allen
    Abstract:
    The core-electron ionization potentials for mono- and di(trifluoromethyl)benzene, for chlorofluoromethanes and for chlorine have been measured in order to give information on the electron distribution in these molecules and to investigate differences between the inductive effect of fluorine and that of CF3. For trifluoromethylbenzene the measured ionization potentials in eV...

  • Satellite structure in the gas-phase X-ray photoelectron spectra of planar unsaturated molecules

    Creator:
    Chambers, Scott Alexander
    Abstract:
    The satellite structure ("shake-up") present in the X-ray photoelectron spectra of several planar molecules containing double bonds has been investigated in the gas phase. This set consists of three five-membered heterocyclic molecules, ethylene and two of its fluorinated analogs, and benzene with three of its fluorinated analogs. In addition, core...

  • Photoelectron spectroscopy of small molecules

    Creator:
    Bomben, Kenneth D.
    Abstract:
    The photoelectron spectra of a series of halogenated molecules have been investigated in the gas phase. Both core-ionization energies and Auger kinetic energies were measured to probe the nature of the interaction that holds a core electron to the molecule. It was found that satellite structure (shake) could be used...

  • Experimental and theoretical investigation of the ability of oxygen-containing molecules to accept charge

    Creator:
    Siggel, Michele Ruth Fisher
    Abstract:
    The question of why carboxylic acids and phenols are stronger acids than alcohols has been investigated experimentally and theoretically. The experimental approach involves comparison of gas-phase acidities and core-ionization energies. The theoretical treatment uses calculated point potentials and acidities. The ease of proton removal is related to two factors known...

    Creator:
    Ji, De
    Abstract:
    In recent years, integrated circuit technology has spawned the development of many low cost and high performance microprocessors and microcontrollers. With these devices, there is an increasing interest in the implementation of distributed control networks, utilizing microprocessors in the control nodes. In this work, a low-cost liquid crystal display (LCD)...
