The use of the complementary information afforded by four types of spectrometry, (mass, infrared, nuclear magnetic resonance and ultra violet), for identification of organic compounds is explained in this text. Throughout, the emphasis is on the relationship between chemical structure and spectral response of the molecule. The book is oriented towards problem solving and includes extensive reference material in the form of charts and tables at the end of each chapter, together with problems to facilitate student comprehension. It also contains an added chapter on new dimensions in NMR spectrometry.
