A reinvestigation of the molecular structure of cyclohexane-1,4-dione by electron diffraction

Creator:: Johnson, Robert David
Abstract:: We have investigated the gaseous structure of cyclohexane- 1,4-dione via electron diffraction. The large amplitude motion, as suggested from spectroscopic, dipole moment and earlier electron diffraction data was studied. The structure was refined in two types of models: a single "distorted boat" conformer, and a model comprised of a superposition...

Laser excited fluorescence and vibrational relaxation of matrix isolated metal oxides

Creator:: Bares, Steven J.
Abstract:: The work presented in this thesis deals with the mechanisms by which a vibrationally excited diatomic molecule gives up its energy to a host monatomic lattice at low temperature. The vibrational lifetimes (v"=1) of the metal oxides Ba0 and A10 in their ground electronic states are studied using pulsed dual...

Exploratory studies of the mechanism of 1,3 sigmatropic ring expansion reactions

Creator:: James, Corinne Patricia
Abstract:: The potassium salts of certain 1-vinylcycloalk-3-en-l-ols have been found to undergo sigmatropic ring expansion rearrangements in HMPA. Preliminary investigations of several benzo-substituted medium ring systems were undertaken in order to determine which of these was best suited for further study. A synthetic sequence leading to the formation of 5-methy1-6-viny1-7,8,9,10-tetrahydro-6-benzocyclo-octenol, which...

Coherent anti-Stokes Raman spectroscopy of gases

Creator:: Guthals, Dennis Marc
Abstract:: The development and applications of a 0.2 cm⁻¹ resolution Nd-YAG laser powered coherent anti-Stokes Raman spectroscopy, CARS, spectrometer for gas phase studies is chronicled in this thesis. Applications including CARS lineshape analysis, resonant CARS, and CARS of transient species and excited state molecules is reported. The intensity of the signal...

Syntheses of large ring hormone analogs

Creator:: Yue, Stephen T.
Abstract:: The (±) 8,9:13,14-diseco-norestradiol, a large ring hormone analog, and its related derivatives, were prepared by a ring expansion approach. The key step of this approach is the establishment of the benzocyclododecenone system via the Caubere reaction. This step not only provides a favorable ring size, it also sets the necessary...

Application of laser spectroscopy to structure and dynamics of small molecular systems

Creator:: Bozlee, Brian J.
Abstract:: A variety of laser spectroscopic methods are employed in this thesis research for studies of CF₃NO, an interesting model photodissociative system, and for investigation of low energy rotations and vibrations of small molecules and low molecular weight clusters in free jet expansions. Nonradiative energy decay for electronically excited CF₃NO is...

Nonlinear Raman spectroscopy of gases

Creator:: Lundeen, Thomas F.
Abstract:: Applications of several methods of coherent nonlinear Raman Spectroscopy have been made in this thesis research. The theory and potential of one of these, Photoacoustic Raman Spectroscopy (PARS), is discussed in chapter two. Experimental results are presented which illustrate the sensitivity of this method and establish sampling conditions for maximum...

Creator:: Miller, Jeffrey Templeton
Abstract:: I. Lithium alkyl and aryl monosubstituted cyclooctatetraenide dianions (Li₂ C₈H₇-R; R = methyl, n- butyl, sec- butyl, tert- butyl, phenyl and benzyl) were synthesized by the reaction of the appropriate organolithium reagent with cyclooctatetraene in diethyl ether or tetrahydrofuran. The reaction occurred cleanly and with good yield of lithium monosubstituted...
