Free exciton magnetoreflectance and magnetization of Cd1-xCrxS (0.0024 < x < 0.0031) were measured at T = 2.0 K and magnetic field up to 5 T. Combining the heavy hole exciton splitting with the magnetization data the exchange integral N0β = +0.46±0.04 eV was evaluated within the framework of mean field approximation.
