Abstract
Theoretical study of the SLR frequency dependence in the triplet excit ed AA-pairs of organic molecular crystals has been carried out at low temperatures. The fine structure energy modulation under the phonon tr ansitions between the ''Davydov components'' of the spectrum is chosen as the major mechanism leading to the SLR. The difference of the ''Da vydov components'' fine structure is connected with the spin-orbit int eraction effects.
