Review of the hardback: 'The book is modern, logical and clear, and will make a good textbook for advanced university courses.' The Times Higher Education Supplement Review of the hardback: 'Alexander Tielens, a well-known and highly-regarded expert in the field, has written this book to meet the need for a comprehensive and wide-ranging high-level textbook on the subject. He has succeeded admirably. ... The text in each chapter is quite dense, and graduate students must expect to work hard; but each chapter is accompanied by a helpful discussion of further reading. The serious student will find the bibliography invaluable. ... This authoritative book, written by an expert in the subject, and - for these days - modestly priced, is highly recommended.' The Observatory Review of the hardback: 'Astrochemistry ... draws in elements of chemistry, physics, astronomy, applied mathematics and computer science ... Covering such extensive subject material in one book would seem to be an impossible task for a single author, but Tielens has pulled it off with this excellent ... volume. ... This is a well-written book that would form a good basis for a postgraduate-level astrochemistry course.' Chemistry World Review of the hardback: '... the book is comprehensive and destined to be a long-term success, both as a text for graduate students and as a reference for the established researcher who needs to fill a knowledge gap.' The Observatory ...a comprehensive overview of the physical processes operating in the gas between the stars, or interstellar medium. One excellent feature is the suggested reading lists at the ends of the chapters, which offer a very nice bibliography of the most important research papers in the field. Choice
