Advances in Physical Organic Chemistry, Volume 53, presents the latest reviews of recent work in physical organic chemistry. It provides a valuable source of information that is ideal not only for physical organic chemists applying their expertise to both novel and traditional problems, but also for non-specialists across diverse areas who identify a physical organic component in their approach to research. Its hallmark is a quantitative, molecular level understanding of phenomena across a diverse range of disciplines. Chapters in this updated release include Theoretical models for activation and reaction energies in chemical reactions, Chiral induction in asymmetric dual catalysis, and The transition state.
