Abstract The results of magnetooptical studies are reported for Cd1−x MnxS crystals with concentrations of the magnetic component x 1=0.0056, and x 2=0.0013, x 1=0.0002 at T=2 K in a magnetic field H⩽3.5 T for H⊥c and H∥c, where c is the hexagonal axis of the crystal. The first reliable confirmation of spin splitting of the exciton reflection spectra of the B exciton transition is successfully obtained as a result of working in an H⊥c experimental geometry. The values of the crystal-field and spin-orbit interaction parameters Δ1, Δ2, Δ3 and the exchange constants J e and J h of Cd1−x MnxS crystals for achieving the best description of the experimental results in the mean exchange field approximation are found on the basis of the data obtained for H⊥c and for H∥c. An analysis shows that the main qualitative features of the observed reflection spectra for the entire series of investigated Cd1−x MnxS crystals can be described only if the condition (Δ1−Δ2)〈0 is satisfied.
