摘要：

The kinetic theory of a new phenomenon, spin catalysis, has been developed. This phenomenon takes place in three-spin systems, when the third radical (or a paramagnetic ion) induces spin conversion in the pair, removes spin forbiddance, and thus changes the reactivity of the first two radicals. Kinetic equations for yields of spin catalyzed reactions have been derived. Conditions for spin catalysis, values of the catalytic effect, and the kinetic behavior are discussed. A new kind of quantum beats in chemical reactions is predicted.
