This book is a well-established guide to the interpretation of the mass, ultraviolet, infrared and nuclear magnetic resonance spectra of organic compounds. It is designed for students of organic chemistry taking a course in the application of these techniques to structure determination. The text also remains useful as a source of data for organic chemists to keep on their desks throughout their career. In the seventh edition, substantial portions of the text have been revised reflecting knowledge gained during the author's teaching experience over the last seven years. The chapter on NMR has been divided into two separate chapters covering the 1D and 2D experiments. The discussion is also expanded to include accounts of the physics at a relatively simple level, following the development of the magnetization vectors as each pulse sequence is introduced. The emphasis on the uses of NMR spectroscopy in structure determination is retained. Worked examples and problem setsare included on a chapter level to allow students to practise their skills by determining the chemical structures of unknown compounds.

This book is a brief view of what has come to be over a period of 13.7 billion years; one not simply, collectively, and consequentially previously told. In the language of yesteryear, it takes us from bang to man; or in that of today, from forces to females. It briefly summarises the evidence that answers the child's question "how did people get here?" But more importantly, on the basis of this, and other, evidence, it then strives to answer their further question "why do people do that?" The answers challenge adults and, looking at the world's problems, are of supreme importance - for the vast majority of the world's populace are either unaware of, or do not accept, many fundamental evidence-based truths. It is to them that "Testing Truths" is addressed.
