Singlet and Triplet Frequency

Recently in the literature n ichov et al. [25] have studied the effect of the spin entanglement in radical ion pairs and the effect this has on the frequency of singlet and triplet recombinations. They have shown that in the absence of spin evolution, the non-local swapping of the spin multiplicity does not in fact manifest itself in the singlet and triplet recombination frequencies. The authors have shown that the average spin state operator can be written in the form
