Essentials of Computational Chemistry provides a balanced introduction to this dynamic subject. Suitable for both experimentalists and theorists, a wide range of samples and applications are included drawn from all key areas. The book carefully leads the reader thorough the necessary equations providing information explanations and reasoning where necessary and firmly placing each equation in context.
This book is a wonderful qualitative survey of the computational chemistry landscape. However, it is not quantitative. Recommend as an introduction, or as supplement to a more quantitative book like Jensen's.
This book is primarily designed for people with strong background in math and computational physics. The author does not provide detailed explanations of the mathematical operations behind the concepts and jumps from one place to another. As the title of the book states, this book is only highlighting the essentials very succinctly.
This book is highly recommended if you do computational chemistry. My particular field requires a lot of ab initio calculations. It is very dense reading, though.
