Vibrational and reorientational lifetimes in liquids determined by Raman spectroscopy

Creator:: Morgan, Larry G.
Abstract:: Studies of anisotropic and isotropic Raman line shape yield information about the rotational motion (rotational correlation function) and non-reorientational (vibrational) lifetimes. The rotational motion of carbon disulfide has been studied previously by the techniques of Raman spectroscopy (6, 43), Rayleigh scattering (43, 46) and direct measurement (47). This work was...

Vibration-rotational studies of isotopic variants of diatomic molecules

Creator:: Orlov, Mikhail L.
Resource Type:: Dissertation

Use of a tungsten filament atomizer in atomic absorption spectrometry

Creator:: Reid, Richard Donald
Abstract:: A nonflame method for atomic absorption spectroscopy is described. A helical tungsten filament from a commercially available 6-V, 4-A light bulb, heated to :incandescence in an argon atmosphere is used to atomize 2-μl aqueous samples for metals analyses. Studies of two hollow cathode lamp tungsten filament orientations, a modulated light...

Theoretical study of beryllium borohydride Be(BH₄)₂

Creator:: Alghamdi, Maha D.
Abstract:: Ab initio calculations using the B3LYP and CCSD(T) methods were employed in this work to explore the most stable structure of the intriguing compound Be(BH₄)₂, for which as many as seven different structures have been proposed in the literature. Use of the B3LYP density functional method with several large basis...

Synthesis and investigation of layered oxides with honeycomb ordering

Creator:: Schmidt, Whitney L.
Abstract:: Synthesis and discovery lies at the core of every field in chemistry. The investigation of the structure-property relationships in compounds known or new is the fundamental purpose of solid state chemistry. Mixing related solid state compounds to form solid solutions can lead to exciting new and/or unexpected properties. Layered compounds...

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...

Spectroscopic investigation of atomic and molecular species formed in a laser microprobe plasma using a wavelenth calibrated tunable dye laser

Creator:: Beenen, Gerhard Joseph
Abstract:: The temporal and spatial characteristics of a laser microprobe plume were investigated using the spectroscopic methods of emission, absorption and fluorescence. The plume was produced by rapid vaporization of a small quantity (1 μg) of a solid sample using a focussed pulsed dye laser (110 MW/cm²). For absorption and fluorescence...

Sample entraining multi-electrode plasma sources for atomic emission spectroscopy

Creator:: Lee, Gae Ho
Abstract:: Plasma sources with multiple electrodes have been developed and characterized in this research for atomic emission spectroscopy. Multi-electrode plasma sources use electrodes to shape the plasma in order to continuously entrain a sample stream in the center of hot plasma, in a manner similar to an inductively coupled plasma (ICP)...
