Optical and EPR investigations of the photochemistry of KCl:OH

Creator:: Bowen, Robert Clifford
Abstract:: The hydroxide ion as a substitutional defect in KC1 can be photo-dissociated at liquid nitrogen temperature by ultraviolet light. The photochemistry of this system was investigated by EPR and optical absorption methods. Theoretical calculations were also performed in an investigation of the KC1:OH system. The bleaching behavior of photochemically colored...

Chemical and physical influences of the atmosphere upon the spatial and temporal characteristics of atomic fluorescence in laser microprobe plumes

Creator:: Lewis, Arnold Leroy
Abstract:: The temporal and spatial characteristics of the plume produced by a laser microprobe, are dependent upon the composition and pressure of the atmosphere surrounding it. It has been shown that certain atmospheres can enhance the analytical signal by increasing the free atom lifetime. Improvements were made to the existing laser...

Some recent developments in the theory of significant figures and their applications to chemical instrumentation

Creator:: Fields, Lawrence D.
Abstract:: Significant figures have been a nebulous area in the physical sciences. The results of a literature survey, and of a questionaire distributed among the Chemistry Department faculty at Oregon State University, revealed widely differing interpretations regarding the proper role of significant figures. The present study has a two-fold nature. First...

Design, construction, and characterization of a six-electrode, direct current, variable length plasma source for atomic emmission spectroscopy

Creator:: Shields, James Phillip
Abstract:: The variable length, six-electrode plasma source for atomic emission spectroscopy described here is operated from three compact, simple, and inexpensive direct current power supplies. The vertical arcs formed between the three electrode pairs completely entrain the sample and are typically operated at 40 V and 20 A. Three concentric quartz...

Syntheses and structures of new inorganic borates

Creator:: Sun, Hongxing
Abstract:: Several new solid-state inorganic borates have been prepared and characterized. Single crystals of the simple orthoborate ScB0₃ were grown and its structure was determined by single-crystal X-ray methods. The new borates Li₃Sc(B0₃)₂, LaSc₃(B0₃)₄, NdSc₃(B0₃)₄, SrNaB0₃, and Li4Ln4MB90₂₃ (Ln = Y, Er, and Gd; M = Al and Ga) were identified...

Stable activable tracers for environmentally significant organic molecules

Creator:: Ghannam, Lina M.
Abstract:: The need for field and laboratory studies of the physical and chemical behavior of environmentally significant organic molecules often poses problems because of the toxicity of the chemical and the difficulty of detecting it at environmentally significant concentrations. Two dysprosium tracers, dysprosium (III) trisacetylacetonate trihydrate and dysprosium(III) trisdibenzoylmethane monohydrate, were...

The adsorption of uranium ions from seawater

Creator:: Fyke, David Ray
Abstract:: The adsorption of uranium ions from seawater could be of importance as reserves of uranium are depleted. The structure, chemical state, and concentration of uranium in seawater have been previously determined. Uranium exists as a charged ion, UO₂(CO₃)₃⁴⁻. The concentration in seawater is 3.3 parts per billion. Previous studies with...

Phenolic oxidative coupling : an approach to the synthesis of pretazettine

Creator:: Chong, Wesley Kwan Mung
Abstract:: Various hypervalent iodine compounds were evaluated as reagents for intramolecular phenolic oxidative coupling. It was found that phenyliodine(III) bis(trifluoroacetate) was effective for the coupling of the monophenolic substrate 13a to 14a under neutral conditions. Vanadium oxytrifluoride and hypervalent iodine compounds were compared as oxidants for the conversion of 32 to...

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...
