Description

This is the perfect complement to ""Chemical Bonding - Across the Periodic Table"" by the same editors, who are two of the top scientists working on this topic, each with extensive experience and important connections within the community.
The resulting book is a unique overview of the different approaches used for describing a chemical bond, including molecular-orbital based, valence-bond based, ELF, AIM and density-functional based methods. It takes into account the many developments that have taken place in the field over the past few decades due to the rapid advances in quantum chemical models and faster computers.

Index

“The two volumes would serve upper-level undergraduates who are well versed in mathematics and chemistry, but they are most suitable for graduate students, faculty, and researchers in chemistry.  The exhaustive chapter references make each book a useful go-to reference source.  Highly recommended. Upper-division undergraduates, graduate students, and researchers/faculty.”  (Choice, 1 May 2015)
