Laser Spectroscopy and Photochemistry on Metal Surfaces
Author: Hai-Lung DaiPublisher: World Scientific
ISBN: 981431725X
Category : Science
Languages : en
Pages : 819
Book Description
Using lasers to induce and probe surface processes has the advantages of quantum state specificity, species selectivity, surface sensitivity, fast time-resolution, high frequency resolution, and accessibility to full pressure ranges. These advantages make it highly desirable to use light to induce, control, or monitor surface chemical and physical processes. Recent applications of laser based techniques in studying surface processes have stimulated new developments and enabled the understanding of fundamental problems in energy transfer and reactions. This volume will include discussions on spectroscopic techniques, energy transfer, desorption dynamics, and photochemistry.

Energetics of Organometallic Species

Pages : 445
Book Description
An overview of modern organometallic thermochemistry, made by some of the most active scientists in the area, is offered in this book. The contents correspond to the seventeen lectures delivered at the NATO ASI Energetics of Organometallic Species (Curia, Portugal, September 1991), plus three other invited contributions from participants of that summer school. These papers reflect a variety of research interests, and discuss results obtained with several techniques. It is therefore considered appropriate to add a few preliminary words, attempting to bring some unity out of that diversity. In the first three chapters, results obtained by classical calorimetric methods are described. Modern organometallic thermochemistry started in Manchester, with Henry Skinner, and his pioneering work is briefly surveyed in the first chapter. The historical perspective is followed by a discussion of a very actual issue: the trends of stepwise bond dissociation enthalpies. Geoff Pilcher, another Manchester thermochemist, makes, in chapter 2, a comprehensive and authoritative survey of problems found in the most classical of thermochemical techniques - combustion calorimetr- applied to organometallic compounds. Finally, results from another classical technique, reaction-solution calorimetry, are reviewed in the third chapter, by Tobin Marks and coworkers. More than anybody else, Tobin Marks has used thermochemical values to define synthetic strategies for organometallic compounds, thus indicating an application of thermochemical data of which too little use has been made so far.

Book Description
Abstract Anion Photoelectron Spectroscopy of Exotic Species By Terry A. Yen Doctor of Philosophy in Chemistry University of California, Berkeley Professor Daniel M. Neumark, Chair Anion photoelectron spectroscopy is performed on a variety of small, unstable species in both the gas and condensed phases. For the gas-phase studies, the properties of the astrophysically significant molecules C3N- and C5N- and the biologically meaningful deprotonated DNA nucleobases were investigated. Spectra of C3N- and C5N- were obtained at 283 nm using slow electron velocity-map imaging and at 213 nm using field-free time-of-flight, respectively. Adiabatic electron affinities for both species, a term value for the first excited state of C5N, and vibrational frequencies for the degenerate cis and trans bending modes of C3N were determined. Spectra of deprotonated thymine and deprotonated cytosine at 213 nm were obtained to explore their excited state dynamics to understand the photostability of DNA. For the condensed phase studies, a new spectrometer, the liquid microjet apparatus, was assembled and used to measure the vertical binding energy of the solvated electron. A microjet flowing a salt solution intersects a laser at either 266 nm or 213 nm. Two photons from a single nanosecond laser pulse are used to first generate solvated electrons using charge-transfer-to-solvent excitation and to then eject them into vacuum, where they are detected using field-free time-of-flight.
