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,...

Using Computational Studies to Characterize Aqueous Metal Clusters : From Spectroscopy to Stability

Creator:: Wills, Lindsay A.
Abstract:: In this dissertation, the spectroscopic properties and thermodynamic stability of a class of materials known as metal oxo and hydroxo clusters are studied. In aqueous solutions, many metals can aggregate into discrete clusters of metals bridged by oxo or hydroxo ligands. These clusters are of particular interest to us for...

Using Computational Methods to Elucidate Reaction Mechanisms for Copper Catalyzed Reactions

Creator:: Caspary, Katherine E.
Abstract:: In this report, two studies are presented that utilize computations to predict and elucidate the reaction mechanisms of two different copper catalyzed reactions. Each study provides insight into the various chemical transformations, as well as the how and why behind regioselectivity and isotopic selectivity. The importance of this research is...

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...

Tracking Photoinduced Primary Events with Femtosecond Stimulated Raman Spectroscopy and Calculations

Creator:: Wang, Yanli
Abstract:: Femtosecond stimulated Raman spectroscopy (FSRS) is a powerful ultrafast technique which can track photoinduced excited state structural events on femtosecond (fs) to picosecond (ps) timescales. In addition to high temporal and spectral resolutions, FSRS provides a broad spectral window from ca. 100—2000 cm-1 for detection, enabling the direct mapping of...

Total Synthesis of Aspidosperma Alkaloids Leuconoxine, Melodinine E and Mersicarpine and Synthetic Studies directed toward the Iboga Alkaloid Ibogaine: Progress directed toward the dimeric Cephalotaxus Alkaloid Cephalancetine C

Creator:: Kim, GilSoo
Abstract:: The first part of this manuscript is about the total synthesis of the aspidosperma alkaloids leuconoxine, melodinine E and mersicarpine. Our synthetic strategy used a radical translocation-conjugate addition cascade to construct the core of the natural product. Specifically, a vinyl radical was generated from the homolysis of the C–I bond...

Thermal [pi]-route rearrangement of 4-cycloheptane-1-methyl acetate

Creator:: Schick, Lawrence Edward
Abstract:: Pyrolysis of 4-cycloheptene-l-methyl acetate under flow conditions at 285° gives only rearranged bicyclic acetates and hydrocarbons rather than the anticipated simple elimination product methylenecyclohept- 4-ene. These rearranged acetates have the same structures and are formed in virtually the same relative percentages as those observed in the "π- route" solvolysis of...
