The results of theoretical and experimental investigations of novel magneto‐optical effects connected with the magneto‐spatial dispersion of the principal dielectric axes are presented. For this purpose the low‐temperature transmission spectra of thin CdSe crystals are measured near the A ( n =1) exciton resonance in the Voigt configuration κ ⟂ H °| C 6 , H ° being the external magnetic field and k being the light wave vector. It is observed that for the polarizer position P | C 6 or P ⟂ C 6 the transmitted light is polarized elliptically and the major axis of the polarization ellipse is rotated with respect to the incident light polarization plane. The derived theory of resonant magneto‐spatial dispersion of the axes is in agreement with experimental data. The constant of the k ‐linear term of the exciton energy spectrum is determined from the comparison of theory and experiment.
