CURTIN HAMMETT PRINCIPLE PDF

It states that, for a reaction that has a pair of reactive intermediates or reactants that interconvert rapidly as is usually the case for conformational isomers , each going irreversibly to a different product, the product ratio will depend both on the difference in energy between the two conformers and the energy barriers from each of the rapidly equilibrating isomers to their respective products. Stated another way, the product distribution reflects the difference in energy between the two rate-limiting transition states. As a result, the product distribution will not necessarily reflect the equilibrium distribution of the two intermediates. The relationship between the apparent rate constants and equilibrium constant is known as the Winstein - Holness equation. The Curtin—Hammett principle applies to systems in which different products are formed from two substrates in equilibrium with one another.
