Gas phase x-ray photoelectron spectroscopy of compounds containing multiply-bonded oxygen

Creator:: Smith, Steven Reid
Abstract:: A new x-ray source capable of operating at up to 80 watts has been designed and developed, and put to use with the Oregon State University Cylindrical Electrostatic Analyzer. The new source produces over four times the photoelectron intensity of its predecessor, from gaseous samples, and accommodates a wider selection...

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...

Diffusion of n-alkanes in polydimethylsilicones

Creator:: Millen, William George
Abstract:: Diffusion of short chain n-alkanes was found to be faster in the polydimethylsilicone elastomer SE-30 than in the polydimethylsilicone oil SF-96-2000. The opposite was true for the longer chain n-alkanes suggesting that choice of stationary phase for gas chromatography would depend on the chain length of sample components. The dependence...

Optical diffraction study of ultrasonic sound velocity in nitrous oxide and ammonia gases

Creator:: Strauch, Joseph George
Abstract:: The velocity of sound in gases was measured, using an ultrasonic wave train as a diffraction grating. The fundamental problems involved in the optical technique are discussed. An apparatus utilizing an objective lens of focal length 1.5 m and aperture f/20 was constructed and used at an ultrasonic frequency close...

Classification of stationary phases in gas chromatography

Creator:: Chong, Elee Elizabeth
Abstract:: Ultraviolet spectroscopy and dispersive solubility parameters correlated to the ratios of retention times have proven valuable in classification of gas chromatography stationary phases by the donor-acceptor properties. Iodine was directly dissolved into stationary phases and the absorption frequency shift of complexes was correlated with the carbon tetrachloride/chloroform retention ratio on...

Infrared investigation of some ferroelectric and related compounds : NH₄NCS, (NH₄)₂SO₄, RbHSO₄, and NH₄HSO₄

Creator:: Oden, L. L. (Laurance L.)
Abstract:: At liquid nitrogen temperature the spectra of sublimed films of NH₄NCS, both as phase I (the usual form stable at room temperature) and phase II (the low temperature form), exhibit detail usually reserved for gases at low pressures. In both phases the symmetry of ammonium ion has degenerated from tetrahedral...

Synthesis of metabolites from the ascomycetes : I. The synthesis and absolute configuration of leptosphaerin : II. Approaches to the synthesis of byssochlamic acid

Creator:: Pallenberg, Alexander J.
Abstract:: Part I. The total synthesis of (+)-leptosphaerin (2), a metabolite of the marine Ascomycete Leptosphaeria Oraemaris (Linder) was achieved, unambiguously establishing both the relative and absolute stereochemistry of this natural product. This synthesis also resolved the long-standing question of which of the isomeric structures 1 or 2 correctly represents the...
