Quantum beats in recombination of spin-correlated radical pairs

The present paper is a review of the current studies of quantum beats in re combination of spin-correlated radical pairs in solutions as well as of fut ure applications of quantum beats technique for studying these pairs. Examp les are given of the use of this method for determining the hfi constants a nd relaxation times of short-lived radical ions, for finding the rate const ants of the reactions of alkane radical cations and for estimating a fracti on of singlet-correlated pairs in the tracks of ionizing particles. The pot entialities of this method, its advantages and limitations are discussed.
