Book Description
This text reviews many of the aspects of the chemistry of the aromatic hydrocarbons and a consensus evaluation of the data by seven of the leading atmospheric scientists. The book covers topics ranging from the relative importance of the compounds in ozone and haze development to methods of estimating elemantary rate coefficients based on structural features of the compounds to mechanisms of aerosol generation and atmostpheric reaction of the polycyclic compounds to photochemical processes. It identifies features of the aromatic hydrocarbons requiring further study and appendicies give the structural formulas and nomenclature of the compounds reviewed in the book.

Book Description
An international team of eminent atmospheric scientists have prepared Mechanisms of Atmospheric Oxidation of the Alkanes as an authoritative source of information on the role of alkanes in the chemistry of the atmosphere. The book includes the properties of the alkanes and haloalkanes, as well as a comprehensive review and evaluation of the existing literature on the atmospheric chemistry of the alkanes and their major atmospheric oxidation products, and the various approaches now used to model the alkane atmospheric chemistry. Comprehensive coverage is given of both the unsubstituted alkanes and the many haloalkanes. All the existing quality measurements of the rate coefficients for the reactions of OH, Cl, O(3P), NO3, and O3 with the alkanes, the haloalkanes, and their major oxidation products have been reviewed and evaluated. The expert authors then give recommendations of the most reliable kinetic data. They also review the extensive literature on the mechanisms and rates and modes of photodecomposition of the haloalkanes and the products of atmospheric oxidation of the alkanes and the haloalkanes, and make recommendations for future use by atmospheric scientists. The evaluations presented allow an extrapolation of the existing kinetic and photochemical data to those alkanes and haloalkanes that are as yet unstudied. The current book should be of special interest and value to the modelers of atmospheric chemistry as a useful input for development of realistic modules designed to simulate the atmospheric chemistry of the alkanes, their major oxidation products, and their influence on ozone and other trace gases within the troposphere.

Book Description
Prepared by an international team of eminent atmospheric scientists, Mechanisms of Atmospheric Oxidation of the Oxygenates is an authoritative source of information on the role of oxygenates in the chemistry of the atmosphere. The oxygenates, including the many different alcohols, ethers, aldehydes, ketones, acids, esters, and nitrogen-atom containing oxygenates, are of special interest today due to their increased use as alternative fuels and fuel additives. This book describes the physical properties of oxygenates, as well as the chemical and photochemical parameters that determine their reaction pathways in the atmosphere. Quantitative descriptions of the pathways of the oxygenates from release or formation in the atmosphere to final products are provided, as is a comprehensive review and evaluation of the extensive kinetic literature on the atmospheric chemistry of the different oxygenates and their many halogen-atom substituted analogues. This book will be of interest to modelers of atmospheric chemistry, environmental scientists and engineers, and air quality planning agencies as a useful input for development of realistic modules designed to simulate the atmospheric chemistry of the oxygenates, their major oxidation products, and their influence on ozone and other trace gases within the troposhere.

Book Description
Oxidation and removal of atmospheric constituents involve complex sequences of reactions which can lead to the production of photo-oxidants such as ozone. In order to understand and model these complex reaction sequences, it is necessary to have a comprehensive understanding of reaction mechanisms and accurate estimates of kinetic parameters for relevant gas-phase atmospheric reactions. This book presents recent advances in the field and includes the following topics: e.g. the oxidation of simple organic compounds, NOx kinetics and mechanisms, OH radical production and rate constants for the OH attack on more complex organic compounds, peroxy and alkoxy radical reactions, photo-oxidation of aromatic and biogenic compounds, and the interaction between radical species.

Book Description
The formation of smog in urban atmospheres involves the interaction of sunlight with an air mixture containing nitrogen oxides and reactive hydrocarbons -- the most reactive class of these hydrocarbons being alkenes. This important new book, by a team of leading atmospheric chemists, reviews and evaluates the existing literature on the atmospheric chemistry of these compounds, focusing on the search for a more quantitative understanding of the phenomenon which can then be applied to control methods. It includes detailed examinations of the reactions of alkenes and even suggests areas for further laboratory studies. This book is ideal for climatologists, meteorologists, and scientists studying the chemistry of the atmosphere and can also serve as a valuable text for graduate courses in atmospheric chemistry and atmospheric science.

Book Description
The aim of this work was to improve the understanding of the OH-radical initiated oxidation of aromatic hydrocarbons (benzene, toluene, p-xylene (BTX) and 1,3,5-trimethylbenzene (TMB)). These mechanisms are considered a major uncertainty in state-of-the-art photochemical models as they are used to predict photooxidant formation from urban air. Differential Optical Absorption Spectroscopy (DOAS) was employed in a systematic outdoor smog-chamber study at the European Photo Reactor (EUPHORE) located at the CEAM-Institute, Valencia/Spain. The available DOAS system was improved for this purpose. The yields of ring-retaining products (phenol from benzene, phenol-type and aldehyde-type compounds from p-xylene and TMB) and glyoxal (from BTX) were investigated. The phenol yield (Y(PHEN)= 53) was found more than two times higher than presently available literature values. Further, the bicycloalkyl-radical pathway was identified as a major pathway from BTX. It was demonstrated that the results of this study are representative for the atmosphere. Deviations from the the degradation pathways of BTX and TMB were further observed under conditions of high NOx (e.g. several ppm). The results of this work indicate that the representations of aromatics in photochemical models need to be updated. The results indicate that the contribution of aromatic hydrocarbons to the formation of photooxidants (i.e. ozone) is underestimated today.
