  • Electrochemistry at a reticulated vitreous carbon flow electrode

    Creator:
    Fahey, Jefferson Vincent
    Abstract:
    The electrochemistry of cadmium at a Reticulated Vitreous Carbon (RVC) electrode has been studied to determine the suitability of RVC as a working electrode for the electrochemical preconcentration of cadmium in the corrosive environment of zirconium dissolved in hydrofluoric acid. The electrochemistry in this investigation deals with deposition of solid...

  • Application of laser spectroscopy to structure and dynamics of small molecular systems

    Creator:
    Bozlee, Brian J.
    Abstract:
    A variety of laser spectroscopic methods are employed in this thesis research for studies of CF₃NO, an interesting model photodissociative system, and for investigation of low energy rotations and vibrations of small molecules and low molecular weight clusters in free jet expansions. Nonradiative energy decay for electronically excited CF₃NO is...

  • Thermolysis of cis,cis,trans-1-phenyl-1,3,5-heptatriene

    Creator:
    Tilton, Mary Lehman
    Abstract:
    Isomerically pure cis,cis,trans-1-pheny1-1,3,5- heptatriene was prepared and cyclized. Ring closure was followed by a 1,5 hydrogen shift, and the only product observed was 1-phenyl -6-methyl -1,3-cyclohexadiene. Rough first order rate constants for thermolysis and the hydrogen shift were determined. Kinetic estimates indicate that the report of disallowed product in a...

  • Ion-pair high pressure liquid chromatography techniques for the determination of quaternary ammonium compounds

    Creator:
    Starbuck, Brian J.
    Abstract:
    Quaternary Ammonium Compounds, Qams, are an important class of chemicals which present interesting challenges to analysts. This thesis reports results of investigations on uses of ion-pairing techniques for separations and detection of Qams. Special apparatus for post-column solvent extraction of liquid chromatographic eluates was developed as part of this work....

  • Coherent anti-Stokes Raman spectroscopy of gases

    Creator:
    Guthals, Dennis Marc
    Abstract:
    The development and applications of a 0.2 cm⁻¹ resolution Nd-YAG laser powered coherent anti-Stokes Raman spectroscopy, CARS, spectrometer for gas phase studies is chronicled in this thesis. Applications including CARS lineshape analysis, resonant CARS, and CARS of transient species and excited state molecules is reported. The intensity of the signal...

  • Factors influencing the competitive rates of free-radical addition of ethyl 2-bromocarboxylates to selected alkene pairs

    Creator:
    Ghodoussi, Vahid
    Abstract:
    A study of the effects of structural modification at the alpha position of ethyl 2-bromocarboxylates on their rates of addition to two alkene pairs was undertaken. In the competition between 3-propoxypropene and 1-octene at 70°, a 37% increase in selectivity was observed in going from carboxylates generating primary radicals to...

  • Laser excited fluorescence and vibrational relaxation of matrix isolated metal oxides

    Creator:
    Bares, Steven J.
    Abstract:
    The work presented in this thesis deals with the mechanisms by which a vibrationally excited diatomic molecule gives up its energy to a host monatomic lattice at low temperature. The vibrational lifetimes (v"=1) of the metal oxides Ba0 and A10 in their ground electronic states are studied using pulsed dual...

  • Target fragmentation in the interaction of 12-16 MEV/NUCLEON ³²S with ¹⁶⁵HO

    Creator:
    Casey, Coreen
    Abstract:
    The target fragment production cross sections, angular distributions, and range distributions have been measured for the interaction of 12-16 A MeV³² S with ¹⁶⁵Ho. The fragment isobaric yield distribution and the moving frame angular distributions have been deduced from the data. Symmetry properties of the moving frame angular distributions have...

  • Nonlinear Raman spectroscopy of gases

    Creator:
    Lundeen, Thomas F.
    Abstract:
    Applications of several methods of coherent nonlinear Raman Spectroscopy have been made in this thesis research. The theory and potential of one of these, Photoacoustic Raman Spectroscopy (PARS), is discussed in chapter two. Experimental results are presented which illustrate the sensitivity of this method and establish sampling conditions for maximum...

    Church, Sara E.
    Abstract:
    The observed and calculated structural parameters of three systems of phosphatidylcholine bilayers in fully-hydrated multilamellar vesicles (MLVs) were determined using x-ray diffraction techniques. The analysis used the x-ray reflections from the low-, intermediateand wide-angle regions of the diffraction patterns in the subgel, gel, rippled and fluid phases to determine the...
