It is shown that spin exchauge interaction can induce oscillations in the recombination probability of spin-correlated radical pairs, even for unresolved EPR spectra of pairs radicals. For the exchange integral values, /, comparable or larger than the EPR spectrum width, the oscillation frequency is

β¦ Synopsis
WC present polarised fluorescence data and a theoretical study of melastic energy transfer m the NH*-11 system Rotatlolll kansfeer hnes are weakly polarrscd, and bnnchmg ratios and pohrhlions depend on the spin component of the radical mitially excited. Polariutron ratios are calculated using the distorted-wave Born approximation with a spin correlated potential operator. Spmdcpendcnt terms are prcdwted to be more reorientmg than the spm-mdepcndcnt part.

The control of the spin of the ground state in molecular clusters behaving like single molecule magnets (SMM) has been an important challenge in coordination chemistry. The spin value is a critical parameter because the barrier for the orientation of the magnetization depends on the square of it. [1
