This book was released on 2008 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis describes the construction of a novel, low-noise laser kinetics spectrometer. A quasi-CW (picosecond pulse), tunable Ti:Sapphire laser is used to detect various transient species in laser flash photolysis kinetics experiments via direct absorption. The spectral range of the laser, when used with a harmonic generator, covers most of the visible wavelength region, allowing for the detection of a wide array of organic radical species. Paired with a temperature-and pressure-controlled flow reactor equipped with a Herriott-type optical multiple pass cell, transient absorptions of ~0.0001 can be measured, corresponding to cross section - concentration products of less than 1x10-7 cm". The flexibility and high sensitivity of this instrument allows direct and accurate measurement of many important transient intermediates in combustion and atmospheric chemistry.Using this instrument, we report the self-reaction rate coefficient of vinyl and allyl radicals. Vinyl iodide and allyl iodide are used as precursors to generate respective radicals via laser-flash photolysis at 266 nm. Second order chemical reactions require an accurate determination of the initial radical concentration, which we determined using direct laser absorption by I atom at 1315 nm. The current study finds the self-reaction rate constant for vinyl radical to be more than a factor of two slower than previous studies and allyl self reaction rate constant to be 50% faster than values reported in the literature. The absorption cross sections of the vinyl radical at 404, 423.2, & 445 nm and allyl radical at 404 & 408 nm are also determined. This thesis also reports measurements of rate coefficients for the reaction of vinyl radical with various alkenes: ethylene, propene, isobutene, 1-butene, and 2-butene,performed over a temperature range of 300 K to 700 K at 100 Torr. The measured vinyl radical disappearance rates compare well with ab initio quantum calculations. The combined measurements and calculations provide improved estimates for other vinyl + alkene reactions.

Available in PDF, EPUB and Kindle. Book excerpt: Reactions of methoxy radicals prepared by the reaction of ground state fluorine atoms with methanol were studied. The intensity of laser-induced fluorescence at 298 nm was used as a measure of methoxy concentration. The presence of various excited molecular products was proven by the analysis of chemiluminescence (CL) spectra. The CL spectra were very complicated and became significantly different when the operating conditions were varied slightly. It was learned that trace amounts of oxygen or air were primarily responsible for these observations.

Download or read book The Mechanisms of Reactions Influencing Atmospheric Ozone written by Jack G. Calvert and published by Oxford University Press. This book was released on 2015-05-13 with total page 608 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ozone, an important trace component, is critical to life on Earth and to atmospheric chemistry. The presence of ozone profoundly impacts the physical structure of the atmosphere and meteorology. Ozone is also an important photolytic source for HO radicals, the driving force for most of the chemistry that occurs in the lower atmosphere, is essential to shielding biota, and is the only molecule in the atmosphere that provides protection from UV radiation in the 250-300 nm region. However, recent concerns regarding environmental issues have inspired a need for a greater understanding of ozone, and the effects that it has on the Earth's atmosphere. The Mechanisms of Reactions Influencing Atmospheric Ozone provides an overview of the chemical processes associated with the formation and loss of ozone in the atmosphere, meeting the need for a greater body of knowledge regarding atmospheric chemistry. Renowned atmospheric researcher Jack Calvert and his coauthors discuss the various chemical and physical properties of the earth's atmosphere, the ways in which ozone is formed and destroyed, and the mechanisms of various ozone chemical reactions in the different spheres of the atmosphere. The volume is rich with valuable knowledge and useful descriptions, and will appeal to environmental scientists and engineers alike. A thorough analysis of the processes related to tropospheric ozone, The Mechanisms of Reactions Influencing Atmospheric Ozone is an essential resource for those hoping to combat the continuing and future environmental problems, particularly issues that require a deeper understanding of atmospheric chemistry.
