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...

Zero Kinetic Energy Photoelectron Spectroscopy of Polycyclic Aromatic Hydrocarbons

Creator:: Harthcock, Colin
Abstract:: In this dissertation, I describe spectroscopic studies of jet-cooled polycyclic aromatic hydrocarbons (PAH) and one nitrogen substituted PAH (PANH) using pulsed field zero kinetic energy (ZEKE) photoelectron spectroscopy and resonantly enhanced multiphoton ionization (REMPI) spectroscopy. Recently, there has been a demand for far-infrared (FIR) spectral information of astrophysically relevant molecules...

Zero kinetic energy photoelectron spectroscopy of jet cooled benzo[a]pyrene from resonantly enhanced multiphoton ionization

Creator:: Zhang, Jie, Harthcock, Colin, Han, Fangyuan, and Kong, Wei
Abstract:: We report zero kinetic energy (ZEKE) photoelectron spectroscopy of benzo[a]pyrene (BaP) via resonantly enhanced multiphoton ionization (REMPI). Our analysis concentrates on the vibrational modes of the first excited state (S₁) and those of the ground cationic state (D₀). Similar to pyrene, another peri-condensed polycyclic aromatic hydrocarbon we have investigated, the...

X-ray structure studies of oriented phospholipid multilayers

Creator:: Lytz, Robert Keith
Abstract:: Lamellar x-ray diffraction was studied from thin films of L-α-1,2-dipalmitoyl lecithin (DPL) and a 1:1 mixture (BrDPL) of L-α-l-palmitoyl-2-(9- bromopaimitoyl) lecithin and its 10-bromo analog. The specimens had high lamellar order, with an upper bound on the mosaicity of 6 mrad (0.4°) for DPL and BrDPL. With various water contents,...

X-ray photoelectron spectroscopy of trifluoromethylbenzenes and chlorofluoromethanes

Creator:: Holmes, Steven Allen
Abstract:: The core-electron ionization potentials for mono- and di(trifluoromethyl)benzene, for chlorofluoromethanes and for chlorine have been measured in order to give information on the electron distribution in these molecules and to investigate differences between the inductive effect of fluorine and that of CF3. For trifluoromethylbenzene the measured ionization potentials in eV...

Wide band gap semiconductors and insulators : synthesis, processing and characterization

Creator:: Hersh, Peter A.
Abstract:: The work presented here is focused on applying basic principles of solid-state chemistry to the study and development of new wide band-gap semiconductors and insulators for photovoltaic and electronic-device applications. Analysis of crystal structure, band structure, optical band gap, morphology and transport properties provides fundamental insight into materials performance as...

Water and methanol adsorption on a series of organic complexes of montmorillonite

Creator:: Carter, Loren Sheldon
Abstract:: Water and methanol adsorption isotherms at 25° and 37° C. were determined on a series of organo-bentonite clays. The clays differed in the length of the carbon chain attached to the amine adsorbed in the cation exchange position. The amines used had carbon chains of 4, 6, 8, 10, 12,...

Vibrational spectroscopy of hydrogen bonded species

Creator:: Hopkins, Glen A.
Abstract:: Due to its importance, the phenomenon of hydrogen bonding has been the subject of much research over the years. Among the different techniques used to study hydrogen bonded systems, vibrational spectroscopy is perhaps the most sensitive because of the striking changes induced in molecular spectra by the formation of hydrogen...
