The magnetic field dependence of the absorption spectra corresponding to the transition 4T1(4F)→2T1(2P) of Co2+ in CsCoCl3 · 2H2O was investigated. In this transition region the Davydov splitting of the exciton lines was observed, and the magnitudes of the intersublattice exciton transfers were estimated. As a result, it was found that the exciton shows the two-dimensional migration closely related to the spin structure.
