This book was released on 1971 with total page 31 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gas phase reactions leading to the formation of singlet metastables in oxygen are being experimentally studied. A flowing afterglow system coupled with titration techniques, metallic surface recombination, and direct sampling and separation of the reactants and products according to their g-factors are used to further specify these reactions. Ground state species have been dominantly found in the H + O(3), NO + O(3) and O + O(3) reactions. (Author).

Download or read book Singlet Oxygen UV A and Ozone written by Lester Packer and published by Academic Press. This book was released on 2000-06-27 with total page 721 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent advances in understanding the biological role of singlet oxygen in the pathways of cellular responses to ultraviolet-A radiation: its key position in photodynamical effects, and its generation by photochemical (dark) reactions, e.g. by cells of the immune system such as eosinophils and macrophages, are the focus of this volume. The new methods and techniques responsible for the rapid progress in this area are presented. The critically acclaimed laboratory standard for more than forty years, Methods in Enzymology is one of the most highly respected publications in the field of biochemistry. Since 1955, each volume has been eagerly awaited, frequently consulted, and praised by researchers and reviewers alike. Now with more than 300 volumes (all of them still in print), the series contains much material still relevant today--truly an essential publication for researchers in all fields of life sciences.

This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ozone formation reaction O+O2+M→O3+M is a unique example of a chemical reaction that leads to an anomalous isotopic composition of the products, most likely due to symmetry - breaking effects. So far, results on other chemical systems that might show similar effects are spurious, even though such claims concerning reactions other than the formation of ozone have been made repeatedly.This applies in particular to the spin forbidden O+CO+M→CO2+M reaction, where two studies report a mass-independent fractionation of about 8%. Nevertheless, the presence of ozone in these experiments raises questions as to the validity of this assertion. We thus make a new attempt to study the O+CO+M reaction in the photoreactor at CCAR (University of Copenhagen) where reagents and contaminants are monitored on-line by FTIR spectroscopy. This study combined with the analysis of the spectral distribution of the employed lamps and isotope kinetic modeling lead to a complete re-interpretation of previous experiments. We conclude that available measurements are more compatible with the hypothesis that there is no mass-independent isotope fractionation in the O+CO reaction. We propose that all observations can be completely explained by an isotope transfer from ozone, involving photolytic production of O(1D) that in turn leads to OH radicals, which then rapidly form CO2 from reaction with CO. We also present a method to produce pure ozone samples and derive an upper limit on nitrogen oxide contaminations based on mass spectrometer measurements. These values will serve as benchmarks values for future studies of ozone absorption cross sections in the IR and UV.

Available in PDF, EPUB and Kindle. Book excerpt: The overall objectives of the present work are to investigate mechanisms of chemical reactions which give rise to electronically excited molecular oxygen and to determine factors responsible for its deactivation in solution, thereby providing the means for optimization of gaseous singlet oxygen formation by homogeneous reaction. Studies have focused upon hypochlorite oxidation of hydrogen peroxide, this reaction having been shown to yield substantial amounts of singlet molecular oxygen . Inasmuch as the redox kinetics were not well-characterized, we have undertaken a thorough analysis of the rate behavior and reaction stoichiometry. Where tractable, measurement of singlet oxygen yields by the various reaction pathways has been made using chemical trapping agents selective for singlet oxygen.(Author).
