'… the authors present some of the most intuitive classical concepts of quantum chemistry in an updated and transparent fashion … The book also contains an interesting discussion of hydrogen-bonding, which may in particular be recommended to biochemists. … definitely requires a careful study … chapter after chapter. The reward will be a deep immersion into the world of modern chemical bonding theory, illustrated for a large number of model systems, and supplemented by carefully worked out examples. … recommended for students and researchers in solid-state physics and materials science.'

This graduate level text presents the first comprehensive overview of modern chemical valency and bonding theory, written by internationally recognised 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, 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 for those with no extensive background in the mathematical machinery of the Schrödinger equation. This book will appeal to those studying chemical bonding in relation to chemistry, chemical engineering, biochemistry and physics.
