Advanced undergraduate and graduate students alike often find this one of more challenging topics in physical chemistry. Robson Wright (chemistry emerita, U. of St. Andrews) therefore takes a progressive approach and proceeds step-by-step with examples, explaining basic and advanced transition state theory, basic and advanced unimolecular theory, potential energy surfaces, simple and modified collision theory, state-to-state kinetics in energy transfer and reaction, energy transfer and molecular beam studies of reactive scattering. Along the way she clearly and fully describes concepts and their importance. She also explains mathematical developments in detail and stresses the significance of the equations. The result is student-friendly while retaining appropriate rigor and is ideal for self-study, although it is also likely to be very useful as a classroom text. Distributed in the US by ISBS.
