The book is designed to present the essentials of the subject to the beginning graduate student as well as to the advanced undergraduate who has had some prior acquaintance with both organic and physical chemistry. Perhaps the book may serve as a text in some of the more theoretically oriented courses in advanced organic chemistry, possible in conjuction with a companion volume on reactioin mechanism. Key Features: In any case, this junction with a companion volume on reaction mechanism. In any case, this book should help the student to acquire the basic knowledge in the field of stereochemistry essential for his later progress. This book is a text, not a treatise, and no pretense is made of complete coverage of the field(Which would require a work of encyclopedic proportions). The choice of topics and the extent ot which they are dealt with ahve necessarily been arbitrary and are in part a reflection of the author's personal interests. Advance apologies are tendered to any of my colleagues who find their own work slighted or their favored subjects discussed inadequately
