This book， the Fifth Edition of a classic work on spectroscopy， concentrates on the practical aspect of using spectroscopic techniques to solve structural problems. It is written at a level that is suitable for an advanced undergraduate or graduate course in applied spectroscopy， but will also give practising chemists a valuable overview of the subject， as well as a good introduction to new techniques （2D NMR and recently introduced methods of producing ions for mass spectrometry）. It is a resource that should be on the desks of all graduate students beginning organic chemistry， and could be read with profit by many of their professors as well. ...
