Highly recommended by CHOICE ".Lewars writes clearly and uses illustrations and examples. End-of-chapter questions are divided into easier and harder levels and a large number of pertinent references are given. The reference material, including books on computational chemistry, appropriate Websites, examples of computational chemistry software with brief descriptions and critiques, and discussion of available hardware is worth the book's price. A welcome contribution to the field. Summing up: Highly recommended." (D.A.

Johnson, Spring Arbor University in CHOICE, Current Reviews for Academic Libraries, March 2004) " The end of puzzlement .outstanding overall impression and didactic value.a bargain for someone moving into the field of molecular modelling." (Nachrichten aus der Chemie, 51:9 (September 2003) [Translated by E. Lewars]. " I'm convinced that it will be a staple for students everywhere . You've done a good job. Apropos PM3: Your approach here is good.

Too often, science is presented dispassionately in books. To see some of the history of these methods makes them more real, I think." (James J.P. Stewart, Stewart Computational Chemistry, USA (September 2003) "I must say that your new text is admirable . you seem to have found the right balance between theory and application which has eluded many in the past. The section on heats of formation was of particular interest to me because that is one of our primary needs, the computation of the thermochemistry of molecules & free radicals encountered in combustion." (Dr.

John M. Simmie, Chemistry Dept. & Environmental Change Institute, National University of Ireland (August 2003) "Your book is beautifully conceived and executed. As you know, computational chemistry is a sprawling subject. Even when one picks out a few core topics to write about, one must still face the difficult challenge of striking the right balance between underlying theory, choosing the right method, and performance of each method. As I say, you have made beautiful choices. I hope the book finds its way on to many chemist (and chemistry student) desks." (Alan Shusterman, Dept.

of Chemistry, Reed College, Portland, OR, USA).
