This accessible book covers group theory, which is a key area of chemistry at undergraduate level. The basic concepts of group theory are introduced, with separate sections on molecular symmetry, the mathematics of group theory and the application of group theory in chemistry. The level of the book is appropriate both for chemistry students who have and who don't have a mathematical background - reflecting the wider range of knowledge and experience of modern chemistry undergraduates. The "workbook" style of the book, where students write their answers to problems and compare them to model answers, helps the student to gain confidence in using group theory in chemistry. Clear, simple diagrams are provided throughout the book, and its attractive workbook format makes this an essential supplementary text for undergraduate chemistry students. Postgraduate chemists and undergraduate students of biochemistry and environmental sciences will also find this book useful.
