Equilibrium Structural Parameters - Vibrational Spectra and Structure

Marc Notes: Includes bibliographical references and indexes. Publisher Marketing: The current volume in the series, "Vibrational Spectra and Structure, "is a single topic volume on gas phase structural parameters. The title of the volume, "Equilibrium Structural Parameters," covers the two most common techniques for obtaining gas phase structural parameters: microwave spectroscopy and the electron diffraction technique. Since the quantum chemical method provides equilibrium geometries, the volume is an attempt to provide a connection between the experimental and theoretical parameters. The book provides a review on molecular structure determinations from spectroscopic data using scaled moments of inertia. The limited number of molecules for which equilibrium parameters have been obtained and the requirement of a large number of microwave data needed to obtain the equilibrium structural parameters is noted. Electron diffraction technique is reviewed, along with a description of how this can incorporate structural information from microwave spectroscopy, vibrational spectroscopy, or theoretical calculations to improve the determination of the structural parameters by electron diffraction studies. Also discussed are the theory and methods of microwave spectroscopy, describing in some detail ro and rs structures as well as rm structures and corrections based on "ab initio" calculations. The accuracy of the molecular geometry predictions by quantum chemical methods is considered in some detail with data presented in graphic rather than tabular form. This makes it possible to readily note the difference in the parameters predicted at the various levels of quantum mechanical calculations. The four authors have provided a coherent description of the various structural parameters obtained experimentally along with treatments needed to extract equilibrium bond distances and angles.

Contributor Bio:  Unknown As a pediatrician, writer, wife, and mother, Perri Klass has demonstrated how medicine is integral to the health of families and communities, and how doctors themselves struggle to balance the conflicting needs of profession, self, and family. As medical director of Reach Out and Read, she encourages other pediatricians to foster pre-reading skills in their young patients. While earning her M. D. at Harvard, Klass contributed articles to "Mademoiselle" and "The New York Times" as well as to scientific and medical journals. She also wrote her first book, "A Not Entirely Benign Procedure "(1987), which chronicles her introduction to medicine and motherhood. In the following years she has continued to publish books, essays, award-winning short stories, a novel, and numerous articles, ranging from professional papers to popular journalism and travel pieces.

Contributor Bio:  Author, Unknown Joseph Barber Lightfoot (13 April 1828 - 21 December 1889), known as J. B. Lightfoot, was an English theologian and Bishop of Durham. Lightfoot was born in Liverpool, where his father was an accountant. He was educated at King Edward's School, Birmingham, under James Prince Lee. His contemporaries included Brooke Foss Westcott and Edward White Benson. In 1847 Lightfoot went to Trinity College, Cambridge, and read for his degree along with Westcott. He graduated senior classic and 30th wrangler, and was elected a fellow of his college. From 1854 to 1859 he edited the Journal of Classical and Sacred Philology. In 1857 he became tutor and his fame as a scholar grew. He was made Hulsean professor in 1861, and shortly afterwards chaplain to the Prince Consort and honorary chaplain in ordinary to Queen Victoria. In 1866 he was Whitehall preacher, and in 1871 he became canon of St Paul's Cathedral. The Times wrote after his death that It was always patent that what he was chiefly concerned with was the substance and the life of Christian truth, and that his whole energies were employed in this inquiry because his whole heart was engaged in the truths and facts which were at stake. In 1875 Lightfoot became Lady Margaret's Professor of Divinity in succession to William Selwyn. In 1879 he was consecrated bishop of Durham in succession to Charles Baring. He soon surrounded himself with a band of scholarly young men. Lightfoot was never married. He died at Bournemouth and was succeeded in the episcopate by Westcott, his schoolfellow and lifelong friend. He served as President of the first day of the 1880 Co-operative Congress. Lightfoot wrote commentaries on the Epistle to the Galatians (1865), Epistle to Philippians (1868) and Epistle to the Colossians. In 1874, the anonymous publication of Supernatural Religion, a work speculated by some to be authored by Walter Richard Cassels, attracted attention. In a series of papers in the Contemporary Review, between December 1874 and May 1877, Lightfoot undertook the defense of the New Testament canon. The articles were published in collected form in 1889. About the same time he was engaged in contributions to William Smith's Dictionary of Christian Biography and Dictionary of the Bible, and he also joined the committee for revising the translation of the New Testament. The corpus of Lightfoot's writings include essays on biblical and historical, commentaries on Pauline epistles, and studies on the Apostolic Fathers.
