"WebCurtin-Hammett Principle. When two conformations, tautomers, or isomers of a starting material are in rapid equilibrium (compared to rate of a reaction), then the product ratio is independent of the ratio of the starting species. Conversely, the product ratio gives no information about which conformation, tautomer or isomer was present in the ... " - Curtin-hammett动力学
