The value of absorption spectroscopy in the isolation of natural products and the determination of their chemical structure is well illustrated by this timely revision of a useful volume the first edition of which appeared in 1935. The increased size and scope of the present book is an index of the tremendous advances which have occurred in the application of absorption spectrum data to the elucidation of the structure of complex molecules. The style of the first edition has been retained. Each section is a chronological treatment of the detection, concentration, isolation, structural determination and, in many cases, synthesis of a particular natural product, with the emphasis on the part played by absorption spectrums in each stage of progress. Thus the volume not only provides spectrosccpic data for the various subjects presented but is, in addition, an excellent summary of our present knowledge of the topics discussed.
