Faraday rotation spectra which may be ascribed to excitons were measured on evaporated films of CuCl. The observed rotation anomaly due to the Z 3 exciton was successfully analyzed in terms of a classical dispersion theory, thereby yielding data of the temperature‐dependent damping constant, the oscillator strength, and the effective g ‐value for the Z 3 exciton. On the basis of the effective mass approximation, estimates were made for the effective mass and g ‐values of the relevant conduction and valence bands.
