The second edition of a bestseller, this book discusses the common structural and stereochemical features of naturally occurring organic compounds. It includes a variety of examples to illustrate varied aspects so that the range of structure and behavior exhibited by these compounds is retained within the set framework. The author explores the increasing application of physical (spectroscopic) methods like IR, NMR, CD, ORD, MS, High Resolution Mass Spectroscopy without undermining the importance of 'classical' chemical methods. The section on problem solving helps to develop an analytical and critical evaluation of the data.
