Zero kinetic energy photoelectron spectroscopy of polycyclic aromatic hydrocarbons

Creator:: Zhang, Jie
Abstract:: In this dissertation, I present electronic spectra of a few polycyclic aromatic hydrocarbons (PAHs): tetracene, pentacene, pyrene, benzo[g,h,i]perylene and benzo[a]pyrene using resonantly enhanced multiphoton ionization (REMPI) and zero kinetic energy (ZEKE) photoelectron spectroscopy. The work of tetracene and pentacene also combine a laser desorption source with a ZEKE spectrometer, demonstrating...

Aryl acetylene substituent effects : the synthesis and application of biaryls

Creator:: Naffziger, Michael R.
Abstract:: The work described herein details the synthesis and application of biphenyls that probe the effects of hydrogen, Cl / Br, and methyl substituents on the aryl ring of the terminal acetylenic carbon. From this work, we successfully developed the rapid synthesis of phenyl acetylenes in 3-4 steps from inexpensive commercially...

Mass spectrometric analysis of bovine neurofilament proteins NF-L, NF-M, and NF-H : peptide mapping, phosphorylation and alkylation site identification

Creator:: Mixon, April E.
Abstract:: Neurofilament proteins are intermediate filaments found in the neuronal cytoskeleton. Phosphorylation of these proteins is considered important for the assembly and stability of the filaments. Accurate molecular weights have been difficult to measure, largely because the high degree of phosphorylation results in M[subscript r]'S that are significantly greater than dictated...

A new trigonal huntite material and subgroup relationships between crystallographic space groups

Creator:: Hruschka, Michael Archimedes and Hruschka, Michael A.
Abstract:: The use of an adjacency matrix to determine distant (not maximal or minimal) subgroup and supergroup relationships between crystallographic spacegroup types is described. Full lists of space-group types that are supergroups and subgroups for every space-group type were compiled. A list of the space-group types connected to each space-group type...

Structure-property relationships of oxides with hexagonal AMO₃ and brownmillerite related structures

Creator:: Jiang, Peng
Abstract:: Transition metal oxides exhibit potential in various application fields due to the special d-electrons. Solid state chemistry focuses on discovering the structure-property relationships. The work in this thesis mainly discusses compounds with hexagonal or brownmillerite-type structure and their practical properties. Hexagonal YIn[subscript 1-x]Fe[subscript x]O₃ (x = 0-0.3, 0.7-1.0) phases have...

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...

Microcomputer controlled chemical and radiochemical separations and analysis

Creator:: Bennett, Casey Wayne
Abstract:: An automated radiochemical flow analysis (ARFA) system was developed which integrates chemical and radiochemical techniques into one system through the use of a microcomputer. The operator, through the microcomputer, controls valves and pumps to transfer sample and reagent solutions to counting loops, ion exchange columns and holdup reservoirs. A Ge(Li)...

Design, construction and application of an instrument for simultaneous measurement of molecular fluorescence, absorbance and chemiluminescence

Creator:: Yappert, Marta Cecilia
Abstract:: An instrument was constructed to measure molecular fluorescence (FL) or chemiluminescence (CL) and absorbance (ABS) simultaneously. The lower, middle, and upper portions of the test solution are probed to obtain ABS, FL, and CL data. Optical fibers are used extensively. The ABS and FL or CL spectra are acquired in...
