This paper is a continuation of earlier work in which the high resolution infrared spectrum of [1.1.1]propellane was measured and its k and l structure resolved for the first time. Here we present results from an analysis of more than 16,000 transitions involving three fundamental bands v₁₀ (E' - A'₁),...
Studies were conducted to investigate the metabolism of
selenium (Se) , and the influences of Se on the metabolism of cadmium (Cd) and inorganic mercury (Hg) in rats, and in ram semen in
vitro. Se-deficient (-Se) or Se-adequate (+Se) rats were injected intraperitoneally with either ¹⁰⁹CdCl₂ (5 μCi/rat) or ²⁰³HgN0₃...
While properties are extremely important from an application point of view, it is crucial to have a detailed understanding of the underlying structural influence. Once a concrete correlation between the structure and the observed property is established, rational design of novel materials with optimized properties can be realized. These optimized...
Monitoring wildlife habitats has become important to forest ecosystem management because it provides valuable information about the response of forests and their species to harvest practices, impacts from recreational use, conservation efforts, and natural and human-caused disturbances. Monitoring is a complex task that requires a variety of abiotic and biotic...
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...
The infrared absorption spectra in the out-of-plane
bending (v₂) region of potassium nitrate were studied for
three phases. Several types of sampled were used: nujol
mulls, fused samples, and N¹⁴-N¹⁵ isotopic mixtures. The
existence of three of the reported polymorphic phases was
confirmed by the spectra. The transitions between phase...
Recombinant human calpain-5 was expressed in insect cells using a baculovirus system. The expressed calpain-5 was purified by both traditional chromatography and by affinity-column chromatography. Both methods yielded active protease. Calpain-5 displayed very limited hydrophobicity. This indicated that calpain-5 is not a membrane binding protein. Calpain-5 had pI of 8.3....
High resolution spectroscopy was used to study the properties of two simple polyatomic molecules, sulfur trioxide, SO₃, and carbon suboxide, C₃O₂. The fundamental modes and several hot bands of the ¹⁸O isotopic fonns of SO₃ (³²S¹⁸O₃ and ³⁴S¹⁸O₃) have been investigated using both infrared spectroscopy and coherent anti-Stokes Raman scattering...
A study was made of the infrared absorption spectrum for
cyanate ion in KCl and KBr host lattices containing small amounts of
calcium or barium ion. Both pellets and single crystals were
scanned during the course of this study. The spectra of the barium
or calcium doped crystals contained many...
