Teaches the use of the complementary information afforded by four types of spectrometry for identification of organic compounds: mass, infrared, nuclear magnetic resonance, and ultra violet spectrometry. Throughout, the emphasis is on the relationship between chemical structure and spectral response of the molecule. Each chapter includes problems to facilitate student comprehension and demonstrate practical aspects of the material. Also provided are extensive reference material in charts and tables at the end of each chapter, solved problems, and 50 sets of Spectra of Compounds to be identified. In addition to extensive updating, the Fifth Edition includes a new chapter on New Dimensions in NMR Spectrometry.
