Overview

This highly effective and practical manual is designed to be used as a supplementary text for the organic chemistry laboratory course - and with virtually any main text - in which experiments are supplied by the instructor or in which the students work independently. Each technique contains a brief theoretical discussion. Steps used in each technique, along with common problems that might arise. These respected and renowned authors include supplemental or related procedures, suggested experiments, and suggested readings for many of the techniques. Additionally, each chapter ends with a set of study problems that primarily stress the practical aspects of each technique, and microscale techniques are included throughout the text, as appropriate. Additional exercises, reference material, and quizzes are available online.

Author Information

M.S., University of California, Berkeley Patty Feist received his Ph.D. in counseling from the University of Kansas. Dr. Feist and co-author Linda Brannon are both professors in the department of Psychology at McNeese State University in Lake Charles, Louisiana, where they have been teaching since receiving their doctorates. After becoming interested in the emerging field of health psychology, Feist and Brannon co-authored the first edition of this text in the 1980s, and they have enjoyed expanding and developing their text along with the field for more than two decades. In addition to his work in health psychology, Dr. Feist has co-authored a text on personality with his son Greg. Ph.D., University of California, Berkeley
