A giant spectral shift has been detected for Raman scattering involving spin flip of a donor-impurity electron in CdS:Mn crystals in a magnetic field. There is a strong correlation between the spin of the donor electron and the magnetic moments of the manganese atoms, which can be seen in the nonzero spectral separation of the Stokes and anti-Stokes components of the spin-flip Raman scattering at Η = 0. This separation amounts to 0.15-0.20 of the maximum separation, observed in saturating fields, and it decreases with increasing temperature.
