Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Alkoxy radicals were produced in a supersonic free-jet expansion and probed via laser induced fluorescence spectroscopy. Over 20 alkoxy radicals containing from 3-12 carbon atoms were investigated at moderate resolution by probing the B-X electronic transition to obtain vibrationally resolved spectra. The interpretation of these spectra in terms of serving as a diagnostic for detection and excited state vibrations and/or different conformations is discussed. The diagnostics for the alkoxy radicals was further extended by studies aimed at obtaining their molecular structure. A few bands in the vibrationally resolved spectra of the primary alkoxy radicals, 1-propoxy, 1-butoxy, and 1-pentoxy were studied under high resolution to resolve the rotational structure. A method for the detailed rotational analysis of these bands was developed which involved a comparison of the experimentally determined molecular constants with those obtained from quantum chemistry computations. The rotational constants of the ground and excited states as well as the spin-rotation constants in the ground state were obtained from these spectra. A rotational bar-coding technique was used to assign the vibronic bands based upon the principle that the rotational structure of a given vibronic band bar-codes for the species carrying the spectrum. The assigned bands can be used as unambiguous diagnostics of the radical species, its structural isomer, and its conformation. The spectra also shed light on the dynamical properties of these radicals which will be important in ultimately understanding their photochemistry.

Available in PDF, EPUB and Kindle. Book excerpt: The human race has altered the chemical composition of the atmosphere, as evidenced by the notorious London smog, photochemical air pollution, acid rain, stratospheric ozone depletion, and elevated greenhouse gas concentrations. The aim of this book series is to present invited summaries of important current research on atmospheric chemistry in a changing world. The summaries range from comprehensive scholarly reviews of major subject areas to more narrowly focused accounts of recent advances by individual research groups. The topics are tied to the important societal issues of air quality, stratospheric ozone depletion, acid deposition, the environmental fate of toxics, and climate change. By gathering these new Advances in one series, we aim to catalyze communication among the many researchers who are studying our changing, contemporary atmosphere.

Available in PDF, EPUB and Kindle. Book excerpt: Organometallic chemistry is an interdisciplinary science which continues to grow at a rapid pace. Although there is continued interest in synthetic and structural studies the last decade has seen a growing interest in the potential of organometallic chemistry to provide answers to problems in catalysis synthetic organic chemistry and also in the development of new materials. This Specialist Periodical Report aims to reflect these current interests reviewing progress in theoretical organometallic chemistry, main group chemistry, the lanthanides and all aspects of transition metal chemistry. Specialist Periodical Reports provide systematic and detailed review coverage of progress in the major areas of chemical research. Written by experts in their specialist fields the series creates a unique service for the active research chemist, supplying regular critical in-depth accounts of progress in particular areas of chemistry. For over 80 years the Royal Society of Chemistry and its predecessor, the Chemical Society, have been publishing reports charting developments in chemistry, which originally took the form of Annual Reports. However, by 1967 the whole spectrum of chemistry could no longer be contained within one volume and the series Specialist Periodical Reports was born. The Annual Reports themselves still existed but were divided into two, and subsequently three, volumes covering Inorganic, Organic and Physical Chemistry. For more general coverage of the highlights in chemistry they remain a 'must'. Since that time the SPR series has altered according to the fluctuating degree of activity in various fields of chemistry. Some titles have remained unchanged, while others have altered their emphasis along with their titles; some have been combined under a new name whereas others have had to be discontinued. The current list of Specialist Periodical Reports can be seen on the inside flap of this volume.

This book was released on 2012-12-06 with total page 529 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the lectures presented at the NATO Advanced Study Institute on "Frontiers of Laser Spectroscopy of Gases" held in the Hotel Golf Mar, Vimeiro, near Torres Vedras, Portugal from 30 March to 10 April 1987. The objective of the meeting was to take stock of the recent technological developments involving lasers and to assess their impact on spectroscopy. The whole range of wavelengths from the far infrared through to the extreme ultraviolet was covered. In addition, specific applications to both atoms and molecules were described. Indeed, one of the most successful and pleasant aspects of the Institute was the joint participation of atomic physicists and molecular spectro scopists, who meet all too rarely these days. The Institute also succeeded in covering a wide time span from the very earliest days of lasers to some of the very latest developments in both lasers and their applications to spectroscopy. There were 14 invited lecturers, giving a total of 40 lectures, and 89 other participants at the Institute. Each of the invited lecturers has contributed a chapter to this volume. In addition, on Thursday 2nd April a special one-day session was held in the Chemistry Department at the University of Coimbra to mark the retirement of Professor Dr. F.

Download or read book Conical Intersections written by Wolfgang Domcke and published by World Scientific. This book was released on 2011 with total page 769 pages. Available in PDF, EPUB and Kindle. Book excerpt: The concept of adiabatic electronic potential-energy surfaces, defined by the Born?Oppenheimer approximation, is fundamental to our thinking about chemical processes. Recent computational as well as experimental studies have produced ample evidence that the so-called conical intersections of electronic energy surfaces, predicted by von Neumann and Wigner in 1929, are the rule rather than the exception in polyatomic molecules. It is nowadays increasingly recognized that conical intersections play a key mechanistic role in chemical reaction dynamics. This volume provides an up-to-date overview of the multi-faceted research on the role of conical intersections in photochemistry and photobiology, including basic theoretical concepts, novel computational strategies as well as innovative experiments. The contents and discussions will be of value to advanced students and researchers in photochemistry, molecular spectroscopy and related areas.
