Nuclear Magnetic Resonance Spectra of Some 1,2,4-triazoles

Nuclear Magnetic Resonance Spectra of Some 1,2,4-triazoles

Date: January 1967
Creator: Creagh, Linda Truitt
Description: In the work undertaken here, NMR has been used to ascertain the structure of some 1,2,4-triazoles. The investigation provides information concerning the structure of potentially tautomeric triazoles such as hydroxy- and aminotriazole. Connected with this aspect of triazole chemistry is the larger problem of mesohydric tautomerism. The present study also yields information for a comparison of substituent effects in triazoles, N-heteroaromatic substances and benzene.

Kinetics and Mechanism Study of Diphenylketene Cycloadditions

Kinetics and Mechanism Study of Diphenylketene Cycloadditions

Date: August 1967
Creator: O'Neal, Hubert Ronald
Description: From a review of the published work in the field of cycloadditions, it is evident that further research is needed to establish the mechanism of ketene cycloadditions. This work was initiated with the intent of obtaining kinetic data which will contribute to the elucidation of the mechanism of ketene cycloadditions.

The Electrochemical Properties of the Mercury/lithium Nitrate-potassium Nitrate Eutectic Interface

The Electrochemical Properties of the Mercury/lithium Nitrate-potassium Nitrate Eutectic Interface

Date: August 1968
Creator: Flinn, David R.
Description: The original purpose of this investigation was to attempt to apply the coulostatic method directly to a molten salt system. The inability to duplicate the reported capacity data for this system resulted in an investigation of the probable cause of this discrepancy between the data obtained by these different methods (14, 15).

Metal Complexes of 2,3-Quinoxalinedithiol

Metal Complexes of 2,3-Quinoxalinedithiol

Date: May 1969
Creator: Ganguli, Kalyan Kumar, 1912-
Description: A series of new planar complexes with the dianion of 2,3-quinoxalinedithiol ligand has been prepared. The complexes have been characterized from the study of their analyses, magnetic moment, conductance, polarograms, electron spin resonance spectra, and electronic spectra, and compared with the available data on the corresponding maleonitriledithiolene and toluene-3,4-dithiolene complexes.

Metal (II) Complexes with N-Salicylideneamino Acids

Metal (II) Complexes with N-Salicylideneamino Acids

Date: August 1969
Creator: Carlisle, Gene Ozelle
Description: Transition metal complexes derived from Schiff bases have rendered an important contribution to the development of modern coordination chemistry. Various stable compounds have been prepared having synthetic, biological, and physicochemical interest. In particular, complexes of salicylaldimines, B-ketoamines, and closely related ligand systems have been investigated.

Some Studies Pertaining to the Biosynthesis and Metabolism of Asparagine and Lysine in Lactobacillus Arabinosus: I. B-Aspartylhydroxamic Acid: Its Action as a Feedback Inhibitor and a Repressor of Asparagine Synthetase in Lactobacillus Arabinosus II. Purification and Properties of Diaminopimelate Decarboxylase from Lactobacillus Arabinosus

Date: August 1969
Creator: Chen, Yueh Tsun
Description: That Lactobacillus arabinosus 17-5, ATCC 8014, can supply its own requirement for the amino acid, lysine, is demonstrated by the fact that the organism is capable of growth in media devoid of lysine. Since the final biosynthetic step in lysine formation in all bacteria studied to date involves the decarboxylation of meso-dlaminopimelic acid (DAP) to produce lysine, it was of interest to determine whether an enzyme catalyzing such a reaction (DAP decarboxylase) is present in L. arabinosus.

The Crystal and Molecular Structures of Tri-(p-Fluorophenyl)-Amine and Tri-(p-Iodophenyl)-Amine

The Crystal and Molecular Structures of Tri-(p-Fluorophenyl)-Amine and Tri-(p-Iodophenyl)-Amine

Date: January 1970
Creator: Freeman, Gerald R. (Gerald Richard)
Description: Because of the need for data on the geometry of nitrogen in arylamines, the determination of the crystal and molecular structures of tri-(p-fluorophenyl)-amine (TFPA) and tri-(p-iodophenyl)-amine (TIPA) was undertaken as the subject of this dissertation.

Electrochemical Disolution of  ZnO Single Crystals

Electrochemical Disolution of ZnO Single Crystals

Date: January 1970
Creator: Justice, David Dixon
Description: The separation of oxidation-reduction reactions into individual half-cells with a resulting "mixed potential" is well known as a dissolution mechanism for metals; however, the mechanism by which non-conducting crystals lose ions to the solution has been studied only slightly.
