This corrected second edition contains new material which includes solvent effects, the treatment of singlet diradicals, and the fundamentals of computaional chemistry.

"Computational Chemistry: Introduction to the Theory and Applications of Molecular and Quantum Mechanics" is an invaluable tool for teaching and researchers alike. The book provides an overview of the field, explains the basic underlying theory at a meaningful level that is not beyond beginners, and it gives numerous comparisons of different methods with one another and with experiment.

The following concepts are illustrated and their possibilities and limitations are given:

- potential energy surfaces;
- simple and extended Hueckel methods;
- ab initio, AM1 and related semiempirical methods;
- density functional theory (DFT).

Topics are placed in a historical context, adding interest to them and removing much of their apparently arbitrary aspect. The large number of references, to all significant topics mentioned, should make this book useful not only to undergraduates but also to graduate students and academic and industrial researchers.

Recensione:

From the reviews of the second edition:

“The purpose of this volume ... is to teach the basic concepts and methods of computational chemistry. ... Lewars ... has provided programs and sufficient information on background and theory for advanced students and scientists to use the programs effectively. ... Literature references are clear, extensive, appropriate, and current, making the volume an excellent research source. ... changes and additions in this edition make it a superior textbook and resource for libraries supporting chemistry and physics programs. Summing Up: Highly recommended. Upper-division undergraduates through professionals/practitioners.” (D. A. Johnson, Choice, Vol. 48 (10), June, 2011)

“There are many textbooks and monographs devoted to computational chemistry but ... Lewars’ is unique. In addition to the principles of computational chemistry, there is a real attempt to provide an insight into the ‘nuts and bolts’ of how various models work. ... will appeal to the fledgling computational chemistry PhD student, the lecturer designing a course, and to the experienced researcher who wishes to do their own calculations and wants to understand more about what is going on inside the ‘black box’.” (Rob Deeth, Chemistry World, October, 2011)

“This text offers a vast and insightful overview for beginner and expert ... . the book is concise and easy to understand, with example solutions and diagrams used effectively to support explanations. The author does an outstanding job of balancing theoretical background with practical application to keep the text engaging and relevant. ... This is an excellent introduction and reference book for anyone with an interest in the subject.” (The Times Higher Education, November, 2011)

Descrizione libreria

Seit �ber 30 Jahren handeln wir mit B�chern. Begonnen hat alles als kleiner Fachbuchhandel in Berlin. Heute sind wir spezialisiert auf den An- und Verkauf gebrauchter B�cher. Noch immer liegt unser Fokus dabei auf den Kategorien: Fachbuch und englischsprachige Literatur. Hinzu kommen B�cher aus allen anderen Genres, wie Belletristik, Biografien oder Kinderb�cher. Unser oberstes Ziel ist dabei die Weiterverwendung von Dingen und die Schonung von Ressourcen. Neben dem Ankauf von privaten B�chern oder Haushaltsaufl�sungen kaufen wir bundesweit komplette Bibliotheken und Buchbest�nde von Institutionen auf, um diese nachhaltig ein weiteres Mal auf den Markt zu bringen. Parallel dazu bietet Buchpark die M�glichkeit, gro�e Mengen einzulagern. Ganze Bibliotheken und umfangreiche Buchbest�nde werden von uns professionell auf Qualit�tsmerkmale hin untersucht und sorgf�ltig f�r den Onlinehandel aufbereitet. Wir schenken B�chern ein zweites Leben.
