High-resolution infrared studies of perdeutero-spiropentane, C₅D₈

Creator:: Erickson, Blake Alexander, Ju, X., Nibler, Joesph W., Beaudry, C. M., and Blake, T. A.
Abstract:: Perdeutero-spiropentane (C₅D₈) has been synthesized and infrared and Raman spectra are reported for the first time. Wavenumber assignments are made for most of the fundamental vibrational modes. Gas phase infrared spectra were recorded at a resolution (0.002 cm⁻¹) sufficient to resolve individual rovibrational lines and show evidence of strong Coriolis...

Examination of low-lying rovibrational states of D₃[subscript h] oblate top molecules using high resolution FTIR and coherent anti-Stokes Raman spectroscopies

Creator:: Kirkpatrick, Robynne
Abstract:: Interesting rovibrational characteristics of two D_(3h) oblate symmetric top molecules were studied. Hamiltonian models for the fine rovibrational level structure of [1.1.1]propellane (propellane) were obtained for many low-lying modes. Ground state parameters (GSP) that are not exclusively K^(2n) dependent were obtained. Initially, the GSP were used in conjunction with density...

Synthetic studies of nonadrides

Creator:: Drapela, Nicholas Ernest
Abstract:: An asymmetric approach to the synthesis of byssochlamic acid (1) is described. Regioisomeric enzymatic differentiation is described in the selective hydrolysis of dimethyl ester 30 by porcine liver esterase. Chiral dimethyl ester 42 was prepared by desymmetrization of cyclopentene 34 using porcine liver esterase. A key intramolecular [2+2]cycloaddition-cycloreversion photometathesis of...

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...

Bridging the Gap Between Equilibrium Properties and Ultrafast Dynamics with Time-Resolved Spectroscopy of Functional Systems

Creator:: Krueger, Taylor D.
Abstract:: Ultrafast spectroscopy has recently gained momentum as a powerful, noninvasive characterization toolset capable of studying a diverse array of samples with applications in chemistry, physics, biology, engineering, and more. Two popular ultrafast spectroscopic techniques include femtosecond transient absorption (fs-TA) and femtosecond stimulated Raman spectroscopy (FSRS). The latter of these techniques...

Mechanistic studies on Re(V) mediated C-O bond transformations

Creator:: Zhuravlev, Fedor
Abstract:: In situ, reduction of Cp*ReO₃ by PPh₃ to form (Cp*ReO)₂(μ-O)₂ allows catalytic deoxygenation of epoxides, however, conproportionation between Reⱽ and Reⱽᴵᴵ species to form clusters of ((Cp*Re)₃(μ-O)₆}²⁺(ReO₄⁻)2 and new compound {(Cp*Re)₃(μ²-O)₃(μ³-O⁾³ReO₃}⁺(ReO₄⁻) leads to removal of rhenium from the catalytic cycle and loss of activity, The epoxide deoxygenation mediated by (Cp*ReO)₂(μ-O)₂...

Synthetic Studies towards Highly Oxygenated Furanyl Diterpenoids

Creator:: Goswami, Subir
Abstract:: The furanyl diterpenoid family of natural products has drawn the attention of both synthetic organic chemists and pharmacologists due to their complex structural architectures and diverse biological activity. Among them, wortmannin has been most extensively studied for biological activities. All these furanyl diterpenoids consist of a highly strained naptha[1,8-bc]furan core,...
