"This is an excellent book to use as an introduction to the techniques and concepts met in theoretical chemistry by undergraduate and beginning graduate students...The organization and style of the book are such that a student would find it easy to read and follow the physical, chemical, and mathematical principles." --Jim McTavish, Liverpool John Moores University

"I wish to thank Professor J. E. House for [the first edition] which I found in the Chemistry library here at Columbia. His book is excellent. It states the basics clearly, and he teaches what a new student needs to know. When I read the author's text he seemed like my own professor because he was so generous." --Alison Winfield, Columbia University

"[This is a] brief need to know introduction to some of the more important topics in elementary quantum mechanics. Over the years I have used two other books similar to this one, both of which were inferior to House's book." --Kurt Christoffel, Augustana College

J.E. House is Scholar in Residence, Illinois Wesleyan University, and Emeritus Professor of Chemistry, Illinois State University. He received BS and MA degrees from Southern Illinois University and the PhD from the University of Illinois, Urbana. In his 32 years at Illinois State, he taught a variety of courses in inorganic and physical chemistry. He has authored almost 150 publications in chemistry journals, many dealing with reactions in solid materials, as well as books on chemical kinetics, quantum mechanics, and inorganic chemistry. He was elected Professor of the Year in 2011 by the student body at Illinois Wesleyan University. He has also been elected to the Southern Illinois University Chemistry Alumni Hall of Fame. He is the Series Editor for Elsevier's Developments in Physical & Theoretical Chemistry series, and a member of the editorial board of The Chemical Educator.
