โœฆ Synopsis


A theory similm :o the mdical pair modei for CIDNP, etc., is used to describe the rate of loss of spin correlation in geminate pairs of radical ions produced by rndiolysis. The ratio of the yields of triplet and sinL,elet excited states and the effects of mqnetic fields are discussed. --When solutions in alkanes are exposed to high 'of the ion pair -a nor.-stationary state. The 0verZl energy radiation, excited states of the solute are wavefunction thei oscillates between singlet and formed by recombination of radical ions [l]. At high triplet because of interaction with the nucIei. It is a concentrations (a 10B2M), the main reactions are: coheient oscillation not 2 relaxation because the time S. -f=+ S+te-,

It has been conf'Lnned in the case of aromatic hydrocarbon,DMA(N,N-dimethytaniline) systems that the ion radical formation occurs mainly from the non-relaxed CT (charge transfer) system before the reLaxed exciplex state is formed. Absolute quantum yields of ion radical formation in acetonitrile have
