' ... will be of use to any chemist with a desire to know about how chemical reactions are described in detail. It is especially useful for the computationally minded researcher who wants to go beyond the standard description of chemical reactions in terms of structures of reactant(s), transition state, and product(s).' Journal of the American Chemical Society, 119:6 (1997)
