Molecular Structure and Energetics Volume 1 Edited by Joel F. Liebman Arthur Greenberg This series has as its theme two of the most widespread, fundamental and important concepts in chemistry: molecular structure and energetics. The scope of the series ranges from species as elegantly simple as elemental boron and carbon to those as ill-defined, yet important, as atmospheric particulates; from rearrangements in clusters to the strain and aromaticity of organic molecules; from the energies of protonation of atoms and diatomic molecules to the binding of substrates to natural and synthetic enzymes. Each volume consists of chapters by leading specialists, and is focused on a common theme. Each essay provides a tutorial review which is generally in a form that blends theory and experiment as well as rigor and intuition. Volume 1, Chemical Bonding Molecules, examines nine topics in the fundamental, conceptual and theoretical framework of molecular structure and energetics. All the essays explicitly compare and interweave findings from experiment and from both calculational and qualitative theory.
