Creator:: Park, Sangmoon, Keszler, Douglas A., Valencia, Melinda M., Hoffman, Randy L., Bender, Jeffrey P., and Wager, John F.
Abstract:: p-type conducting films of α- BaCu₂S₂ have been deposited onto glass and KBr substrates, yielding a conductivity of 17 S/cm and a Hall mobility of 3.5 cm²/Vs. For a 430-nm-thick film, the optical transparency approaches 90% in the visible portion of the spectrum at 650 nm, and a transparency of...

Biosynthesis of blasticidin S : mechanistic and stereochemical investigations

Creator:: Prabhakaran, P. C.
Abstract:: Feeding of [3-¹³C, 2-¹⁵N]arginine, 38a, unequivocally established that the β- arginine moiety of blasticidin S, 1, was formed from α-arginine by an intramolecular migration of the α-amino group to the β- position. Further feedings using chirally deuteriated arginines 38e and 38f revealed that the aminomutase process occurred with inversion of...

High resolution spectroscopic studies of ³²S¹⁶O₃ and ³⁴S¹⁶O₃

Creator:: Barber, Jeffrey
Abstract:: The two sulfur isotopomers of sulfur trioxide, ³²S¹⁶O₃ and ³⁴S¹⁶O₃, have been studied via high resolution infrared and Coherent anti-Stokes Raman (CARS) spectroscopy. The v₁ symmetric SO stretching Q-branches observed by the latter are quite different, being especially complex for ³²S¹⁶O₃ Understanding this band structure required analysis of infrared-active hot...

Decomposition of di-p-toluenesulfonyl-hydrazones

Creator:: Bradway, Diane Elizabeth
Abstract:: Thermal decomposition of several di-p-toluenesulfonylhydrazones was studied. It was found that the carbene decomposition of tetramethyl-1,3-cyclobutanedione, di-p-toluenesulfonylhydrazone gave two products resulting from rearrangement. One was identified as 2,5-dimethyl-1,3,4-hexatriene. A tentative structure for the second was proposed. During the course of the study, a more convenient procedure for thermal decompositions was...

Measurement of the fusion probability, P[subscript CN], for hot fusion reactions

Creator:: Yanez, R., Loveland, W., Barrett, J. S., Yao, L., Back, B. B., Zhu, S., and Khoo, T. L.
Abstract:: Abstract: Background: The cross section for forming a heavy evaporation residue in fusion reactions depends on the capture cross section, the fusion probability, P[subscript CN], i.e., the probability that the projectile-target system will evolve inside the fission saddle point to form a completely fused system rather than reseparating (quasifission), and...

Magnetic properties of an analog compound for cytochrome P-450

Creator:: McCann, Steven Wayne
Abstract:: This thesis describes a Mossbauer effect and electron paramagnetic resonance study of iron (III) tetraphenylporphyrinatobenzenethiolate benzene thiol, an analog compound for bacterial cytochrome P-450. The compound is unusual in that it provides a model for the two ferric reaction states of cytochrome P-450. The iron in the model compound exhibits...

Direct atom transfer vs. ring expansion in reaction of rhenium oxo complexes with cyclooctene epoxides and episulfides

Creator:: Khownium, Kriangsak
Abstract:: The rhenium (V) complex Tp'ReO₂ (Tp' = hydrido-tris-(3,5- dimethylpyrazolyl)borate), generated in situ from PPh₃ reduction of Tp'Re0₃, reacts with small ring heterocycles such as epoxides and episulf ides. The strained trans-cyclooctene ring provides an unusual thermodynamic bias against direct atom transfer, but trans-cyclooctene oxide still produces substantial amounts of trans-cyclooctene....
