A study of the photolysis of the aqueous thymine system at 214 nm, 229 nm and 254 nm

Creator:: Satcher, Robert Lee
Abstract:: The photolysis of the aqueous thymine system has been investigated at 214 nm, 229 nm and 254 nm at room temperature. Products of photolysis have been identified as hydrogen peroxide, 6-hydroxy-5- hydroperoxy thymine and tentatively 5-hydroxy-6-hydroperoxy thymine. These together with thymine loss, were determined quantitatively under a variety of conditions....

Fluorescence studies on the bases of the nucleic acids in solution at room temperature

Creator:: Hauswirth, William Walter
Abstract:: Fluorescence of adenine, guanine, thymine, cytosine, and uracil has been detected at room temperature in neutral aqueous solution using a digital signal accumulation technique and right angle fluorescence detection from solutions with absorbances between 0. 4 and 0. 7. The quantum yields are respectively 2.6 x 10⁻⁴, 3.0 x 10⁻⁴,...

Hydroperoxide formation in the radiolysis of aqueous DNA and the pyrimidine bases

Creator:: Schwiebert, Maris Carol
Abstract:: The formation of cytosine hydroperoxide was detected in aqueous cytosine solutions irradiated with Co-60 γ-rays at pH 2. The nucleotide of cytosine, cytidylic acid, forms a hydroperoxide which was detected in neutral solution. The stability of the hydroperoxides of cytosine, thymine, and their nucleotides was found to be a function...

Computational Rationalizations of Mechanism and Stereocontrol in Small-Molecule Lewis Base Organocatalysis

Creator:: McCauley-Walden, Daniel W.
Abstract:: My work has focused on investigating synthetic organic reactions using applied computational methods. Non-covalent interactions are critical to catalysis, mechanism, and stereoselectivity, with the most prominent interaction for isothioureas being the S···O contact between the catalyst sulfur atom and the oxygen of the acyl group. A comprehensive joint experimental and...

Porous metal-organic materials for gas capture

Creator:: Rookard, Tanner Daniel
Abstract:: Metal-organic polyhedra (MOPs) are discrete molecules comprised of a metal and interconnecting ligands. The resulting MOP structures are porous cages, and to date, they have shown great promise toward gas capture. Ammonia is a hazardous gas that is produced in enormous quantities for use in fertilizers. In this talk, I...

Unlocking Water's Potential for Energy Storage: Abundant Materials for a Ubiquitous Problem

Creator:: Leonard, Daniel P.
Abstract:: Water is an absolute necessity for life as we know it. It provides a useful medium in which chemical reactions take place that allowed for the development of single cellular organisms. When combined with the evolutionary accident that was pho- tosynthesis, water became not only a useful medium chemical reactions,...

Reactions and stereochemistry of thiolato and sulfenato cobalt (III) complexes

Creator:: Herting, Daniel L.
Abstract:: This thesis describes a study of the synthesis, stereochemistry, and reactivity of cobalt(III) cysteinato (CyS) and related thiolato complexes. The preparation of [Co(en)₂CyS]⁺ resulted in a product solution containing a mixture of diastereomers in the ratio 2.3:1 (Δ:A). The isomers were separated by ion exchange chromatography, and their absolute configurations...
