Traditionally, physical organic chemistry and theoretical organic chemistry have been treated as separate disciplines. This new book bridges these two areas in order to give the reader a new perspective on the nature of organic reactivity. A key element of this new approach is the author's extensive nonmathematical description of the recently developed curve-crossing model that describes why chemical reactions have an activation barrier, and specifies the factors that govern the barrier heights. In addition, the author draws from physical chemistry and transition-metal chemistry to present an...
