X-ray structure studies of oriented phospholipid multilayers

Creator:: Lytz, Robert Keith
Abstract:: Lamellar x-ray diffraction was studied from thin films of L-α-1,2-dipalmitoyl lecithin (DPL) and a 1:1 mixture (BrDPL) of L-α-l-palmitoyl-2-(9- bromopaimitoyl) lecithin and its 10-bromo analog. The specimens had high lamellar order, with an upper bound on the mosaicity of 6 mrad (0.4°) for DPL and BrDPL. With various water contents,...

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...

Using Computational and Statistical Methods as an Aid to Study Environmentally Relevant Organic Molecules

Creator:: Dorn, Shelby E.
Abstract:: In this report, three studies are presented that utilize computations to predict transformations, identities, and properties of environmental organic molecules. Each study shows how computations can lead to models of chemical behavior. The importance of this research is rooted in the need for understanding how human behavior and health intersect...

Use of Targeted and Non-Targeted Analysis to Study Complex PAH Environmental Mixtures

Creator:: Chibwe, Leah
Abstract:: Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous contaminants formed from the incomplete combustion of organic material. These contaminants are of concern because of their widespread presence in the environment and toxic properties. In addition, PAHs encompass a class of diverse compounds with varying physicochemical properties and exist in the environment as...

Two studies concerning rare earth elements : I. Rare earth DTPA complexes as estuarine hydrological tracers : II. Rare earth elemental concentrations in some Pacific Northwest rivers

Creator:: Keasler, Kenneth M.
Abstract:: Two studies were conducted involving rare earth elements. In the first study, the use of rare earth diethylenetriaminepentaacetic acid (DTPA) complexes as stable actiable tracers, a method of stable-isotope tracing with post-sampling neutron activation analysis, was explored. The persistence of rare earth DTPA complexes in estuarine waters was measured in...

Time-of-flight scattering and recoil spectrometry (TOF-SARS) applied to molecular liquid surfaces : a new approach to surface composition and orientation

Creator:: Gannon, Thomas J.
Abstract:: In spite of their importance in many systems, liquid surfaces have been explored at the microscopic level to a much lesser extent than solids. Most surface analysis must take place in vacuum, a major drawback for liquids. The technique of time-of-flight scattering and recoil spectrometry (TOF-SARS) has been applied to...

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...
