Part A: Some Reactions Of Norbornene Oxide: Part B: Arylnorbornene Oxides, Thomas J. Gerteisen

Doctoral Dissertations

Part A: In this thesis research on the action of Grignard reagents with with norbornene oxide has been initiated and found to be of possible synthetic utility.

Part B: The structure of the product of the acid catalyzed dehydration of 2-p-anisylnorbornane-2, 3-cis-exo-diol in hydrochloric acid-tetrahy-drofuran has been reassigned. It was discovered, on the basis of further data, that the structure of the high melting solid was that of the dimer of the epoxide, a p-dioxane, rather than the epoxide itself. This change was proposed for many reasons. A near total nmr analysis of the compound …

Cobalt(Iii) Complexes With 1,2-Propanediaminediacetic Acid, Paul John Magnell

Masters Theses

Introduction

Aminocarboxylic acid cobalt(III) complexes have been of interest to inorganic chemists since 1909 when Ley and Winkler isolated violet and rose colored geometric isomers of tris amino acid complexes of glycine and alanine.¹ More recently, considerable interest has been shown in the study of the stereochemistry and optical activity arising from configurational and vicinal interactions of these complexes. Nuclear magnetic resonance of the methylene protons on the carboxylate portion of the coordinated ligand has also been studied.

Of immediate interest to this study is the stereo-chemistry of complexes containing flexible tetradentate ligands. A tetradentate ligand may be constructed …

Computer Implemented Synthesis Of Multiple Level Combinational Networks, Alfredo Caldwell

Masters Theses

The purpose of this investigation has been to implement, in the form of computer programs, two algorithms which are used in the synthesis of multiple level combinational networks. The algorithms implemented were devised by Professor Paul E. Wood, Jr., of M.I.T., and by Professor Eugene L. Lawler, of The University of Michigan. In the course of the investigation a more efficient way of implementing the two algorithms was discovered. The combined version of the algorithms takes advantage of the best features of the original algorithms.

In the synthesis of multiple level combinational networks minimal complexity is high desirable. The whole …

Geology, Geochemistry And Lava Tubes In Quaternary Basalts, Northeastern Part Of Zuni Lava Field, Valencia County, New Mexico, James Douglas Causey

Earth and Planetary Sciences ETDs

Basaltic volcanism in the northeastern part of the Zuni lava field is related to a north-northeast trending regional fracture system. This is shown by elongation of centers and their alignment. However, .the fractures do not control the direction of lava tubes.

There are three distinct stages of volcanic activity common to the Zuni lava field:

1) early pyroclastic eruptions,

2) quiescent flows or fissure eruptions􀀅

3) late pyroclastic eruptions.

Evidence for the first stage is sometimes lacking, but the second and third stages can always be seen.

The basalts range from weakly tholeiitic to alkali in nature. Potassium content varies …

I. Existence Of Eigenvalues For Integral Equations; Ii. A Collocation Method For Boundary Value Problems, Robert Dodd Russell

Mathematics & Statistics ETDs

I. The existence of eigenvalues is shown for certain classes of integral equations with continuous kernels. A number of interesting and useful results are thereby treated in a unified and relatively elementary way. The simplicity of these new proofs make the results accessible to introductory courses on the theory of integral equations.

II. Collocation with piecewise polynomial functions is developed as a method for solving two-point bour:rlary value problems. Convergence is shown for a general class of linear problems and a rather broad class of nonlinear problems. Some computational examples are presented to illustrate the wide applicability and efficiency of …

Liquid Scintillators. The Photooxidation Of 2,5-Diphenyloxazole, Margaret E. Ackerman

Chemistry and Chemical Biology ETDs

Mackay had found that prolonged ultraviolet irradiation of solutions of 2,5-diphenyloxazole (PPO) (1) in toluene resulted in the formation of an insoluble crystalline product 2 which accumulated above the meniscus; the formation of 2 was dependent upon the presence of dissolved oxygen and water in the solutions. The Compound 2 was not a simple degradation product of PPO (1); elemental analysis was compatible with the empirical formula C22H17O5N and the thermal decomposition of 2 gave equal molar amounts of carbon monoxide, benzoic acid, and dibenzamide. The study described in this dissertation was initiated to establish the structure of 2 and …

Part I. The Stereochemistry Of Carbanions Formed By Base Catalyzed Decomposition Of Azoacetates Part Ii. Anomalous Decarbonylation Of 4 –Substituted Carboxylic Acids With Thionyl Chloride, Tai-Shun Lin

Dissertations

Introduction

Although the stereochemical capabilities of carbonium ions have been extensively investigated, the stereochemical fate of carbanions has been subjected relatively little to systematic scrutiny. The fact that only a limited number of clean-cut sources of carbanions are available has added difficulty to such investigations.

The stereochemical capabilities of carbanions has been extensively and thoroughly examined in recent years by Cram and coworkers. However, the carbanion carbon developed in the reactions employed was bonded in every case to an unsaturated (usually aromatic) group. No fully aliphatic carbanion has been subjected to such a stereochemical study.

Electron Optical Study Of A Secondary Electron Multiplier, Chang Min Shen

Dissertations and Theses

Electron orbital theory was applied to the design of the geometrical structure of an electron multiplier for an image intensifier. A special structure satisfying production requirements was studied. Electron optical calculations consisted of determining the potential distribution and tracing the electron trajectories. Liebmann's procedure was used to solve Laplace's equation with constant potentials on the multiplier electrodes as boundary conditions. The trajectories were determined by solving the equation of motion in an electrostatic field using a Runge-Kutta procedure. The initial conditions for the trajectories were the initial energies, initial positions, and the initial directions of the secondary electrons. The plotted …

Rapid Sediment Analyzer calibration was conducted by comparison of sieving and settling results of similar sands.

The study area was divided into sediment provinces by both a qualitative procedure (grain size and topography) and a quantitatively procedure (factor-vector analysis). Qualitative provinces are beach and surf, upper shore face, lower shore face, sea floor, and terminal shoals. The berm fines from each terminal …

Erasure Of Sediment Surface Features By Mellita Quinquiesperforata (Leske), Walter Richard Boehmer

OES Theses and Dissertations

Erasure of sediment surface features by individuals of the species, Mellita guinguiesperforata, observed in this study suggests that all members of the sub-order, Scutellina, are able to erase sediment surface features. Sweep time, the time needed to erase the surface features of an area, depends on the population density, individual size, and speed of movement of the sand dollars. Assuming their pattern of movement as random, the following equation can be used to determine sand dollar sweep time,

T - 3.2 N^-0.76 (W / S) (A/ W² )^1.21

where T is sweep time, N is the …

The complexes were shown to be d6 strong field systems by magnetic susceptibility measurements performed at room temperature in air.

Room temperature absorption spectra in the visible and near-ultraviolet were measured in solvents of different polarities (H₂O, MeOH, CH₃CN, DMF, CHCl₃) and solvent shifts of the band maxima of 0.3 to 3 kK were found. Low temperature (approximately 82-90°K) absorption spectra …

Quantitative Spark-Source Mass Spectrometric Techniques For The Simultaneous Determination Of The Lanthanide And Actinide Elements In Microgram And Sub-Microgram Transuranium Samples, Joel Avery Carter

Doctoral Dissertations

The work presented encompasses techniques developed for the analysis of certain rare earth and actinide elements in solutions containing highly radioactive transuranium elements. Advantage was taken of the high inherent resolution and sensitivity of the rf spark-source mass spectrometer in the development of qualitative and quantitative procedures where an analysis can be made on a total sample of <1 to 10 μg. Parameters for the Associated Electrical Industries' MS-702 spark-source mass spectrometer were adjusted so that mass-to-charge ratios in the range of 10 to 310 could be subjected to qualitative analysis. For quantitative assessment of impurities in a transuranium solution, relative sensitivity factors were established with respect to erbium, the internal standard, for rare earth elements and for thorium, uranium, neptunium, americium, curium, berkelium, and californium.

A special glove box was designed, fabricated, and used on the source end of the mass spectrometer so that samples of the transuranium elements could be run safely. Transuranium element with α-emitting radioactivity up to 10¹⁰ dpm were processed through the …

Photochemical Reduction Of Benzophenone By 2-Butyne-L, 4-Diol And Photochemical Solvolysis Reactions Of Beta-Phenethyl Compounds, Kenneth Lawrence Gordon

Honors Theses

The irradiation of a dioxane solution of benzophenone in the presence of 2-butyne-1, 4-diol leads to reduction of the ketone rather than addition across the triple bond of the alkyne. However, great difficulty was encountered in identifying the product due to the formation of an organic complex involving benzopinacol and the dioxane. Nuclear magnetic resonance and ultraviolet spectral data confirm the presence of the complex. An attempt was made to induce a known ground state reaction by photochemical means. This ground state reaction is known to proceed through an ethylene phenonium ion intermediate. Both β-phenethyl bromide and β-phenethyltrimethylammonium tetrafluoroborate were …

Determination Of Ring Orientation In Diphenylmethane And Derivatives, Patrick Michael Comi

Honors Theses

Nuclear Magnetic Resonance Spectrometry, like infrared, visible, and ultraviolet spectrometry is a form of absorption spectrometry. Certain nuclei can absorb electromagnetic radiation in the radiofrequency range. These nuclei are able to absorb this energy because they “spin” about their center axis generating a dipole along it. Protons are among those nuclei that absorb radiofrequency energies. If a proton is placed in a magnetic field its dipole can be in one of two possible orientations. It can be in a low energy state aligned with the field, or a high energy state, a spinning proton will process about an axis at …
