This textbook develops the foundations of Lewis- and Pauling-like localized structural and hybridization concepts to present the first modernized overview of chemical valency and bonding theory. Directly based on current computational technology, it serves as both a general textbook exposition of modern Lewis, hybridization, and resonance concepts and a comprehensive compilation of NBO-based bonding descriptors--for prototype molecular and supramolecular organic and inorganic species.

Because it is grounded in math, chemical thermodynamics is often perceived as a difficult subject and many students are never fully comfortable with it. The first authoritative textbook presentation of equilibrium chemical and phase thermodynamics in a reformulated geometrical framework, Chemical and Phase Thermodynamics shows how this famously difficult subject can be accurately expressed with only elementary high-school geometry concepts. Featuring numerous suggestions for research-level extensions, this simplified alternative to standard calculus-based thermodynamics expositions is perfect...

This book explores chemical bonds, their intrinsic energies, and the corresponding dissociation energies which are relevant in reactivity problems. It offers the first book on conceptual quantum chemistry, a key area for understanding chemical principles and predicting chemical properties. It presents NBO mathematical algorithms embedded in a well-tested and widely used computer program (currently, NBO 5.9). While encouraging a -look under the hood- (Appendix A), this book mainly enables students to gain proficiency in using the NBO program to re-express complex wavefunctions in terms of...
