摘要：

The application of the saturation-transfer method with Fourier transform NMR to multisite spin systems is discussed. Three-site exchange is considered in detail: exact equations for the calculation of rate constants are given, and approximate equations are presented which may be used in certain simplifying situations. The method is illustrated with several examples of three-site proton exchange: acetamide in fuming sulfuric acid, acrylamide in ethylene glycol, and acetamidinium ion in ethylene glycol. In each case, all six rate constants have been measured and are nonzero. © 1979.
