  • Integration methods for enzymatic analysis response curves which show maxima, minima or inflections

    Creator:
    Radke, Garold E.
    Abstract:
    Integration methods for enzymatic reactions were applied to transducer response vs. time curves which exhibit maxima, minima or inflections. The difference between the integral of the time dependent response and the initial response, often zero, is related to the initial enzyme activity or substrate concentration. Fluorescence response curves which exhibit...

  • The development of a high spectral-resolution laser-excited molecular fluorescence system and its application to gas chromatography and the determination of polynuclear aromatic hydrocarbons

    Creator:
    Hein, Scott J.
    Abstract:
    A high-spectral resolution laser-excited molecular fluorescence system was developed that utilizes a pulsed supersonic expansion to simplify the fluorescence excitation spectra of large, gas-phase aromatic molecules diluted in an excess of a monatomic gas. A microcomputer was used to control and synchronize the instrumental components, which included a Chromatix CMX-4...

  • Biological oxidation of sorbitol

    Creator:
    Cummins, Joseph Thomas
    Abstract:
    The oxidation of sorbitol by soluble extracts of A. suboxydans proceeds by two pathways depending upon which pyridine nucleotide is present. In the presence of TPN, sorbose is formed. In the presence of DPN fructose is produced. Both products of the oxidation of sorbitol have been identified by paper chromatography,...

  • Reactions of organoboranes

    Creator:
    Thompson, Thomas Myron
    Abstract:
    An examination was made of some reactions involving a transfer of carbon from boron to carbon. In the case of the reaction of a C[subscript n] alkylorganoborane with dichlorocarbene the intermediate was a C[subscript n]₊₁ chloroalkylorganoborane. Oxidation of this intermediate yielded an homologous acid (33%) and the usual alcohol (66%)....

  • 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...

  • Steroid dialkylcarbene reactions

    Creator:
    Dixon, Dale David
    Abstract:
    Steroid carbenes have been investigated as synthetic intermediates. Basic decomposition of 4-en-3-one tosylhydrazones (and other A-ring systems) gives varying amounts of 2, 4-dienes, and solvent derived products with diglyme, heptane, tetrachloroethylene, carbon tetrachloride, benzene and cyclohexene. A method for separating complex product mixtures was developed and a study of the...

  • 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...

  • Formation of alkyl-and dialkylcarbenes. The 3-cyclohexenyl carbinyl carbene system

    Creator:
    Crouse, Dale McClish
    Abstract:
    The 3-cyclohexenyl carbinyl carbene species was formed by the thermal decomposition of the p-toluenesulfonylhydrazone sodium salt and by oxidation of the hydrazone. Several oxidizing agents were studied. The products were investigated under aprotic and protic conditions and at various temperatures. The diazocompound was formed as an intermediate and found to...
