Description of Valency and Bonding 1st Edition (PDF)

Valency and Bonding written by Frank Weinhold & Clark R. Landis is a great Chemistry book for chemical bonding studies available in (PDF) download. In identifying the features that distinguish this book from many predecessors, we do not attempt to conceal the enormous debt of inspiration owed to such classics as Pauling’s Nature of the Chemical Bond and Coulson’s Valence. We aspire neither to supplant these classics nor to alter substantially the concepts they expounded. Rather, our goal is to take a similarly global view, but develop a more current and quantitative perspective on valency and bonding concepts such as hybridization, electronegativity, and resonance, capitalizing on the many advances in wavefunction calculation and analysis that have subsequently occurred. We hope thereby to sharpen, revitalize, and enhance the usefulness of qualitative bonding concepts by presenting a “twenty-first-century view” of the nature of chemical bonding.

This graduate-level text presents the first comprehensive overview of modern chemical valency and bonding theory, written by internationally recognized experts in the field. The authors build on the foundation of Lewis- and Pauling-like localized structural and hybridization concepts to present a book that is directly based on current ab initio computational technology.

The presentation is highly visual and intuitive throughout, being based on the recognizable and transferable graphical forms of natural bond orbitals (NBOs) and their spatial overlaps in the molecular environment. The book shows applications to a broad range of molecular and supramolecular species of organic, inorganic, and bioorganic interest. Hundreds of orbital illustrations help to convey the essence of modern NBO concepts in a facile manner for those with no extensive background n the mathematical machinery of the Schr ̈odinger equation. This book will appeal to those studying chemical bonding in relation to chemistry, chemical engineering, biochemistry, and physics.
