"... where would a mechanistic, physical or even a synthetic organic chemist go to become more fluent in the use of free energy relationships? What a good resource when we teach this material to undergraduate and graduate students? I believe the answer to both questions is Free Energy Relationships in Organic and Bio-Organic Chemistry ... The book would be a nice supplement to a larger tome used in a senior or graduate level course in organic or physical organic chemistry. It would be an excellent textbook for a specialty course in free energy relationships. "
