High magnetic field electron paramagnetic resonance experiments have been performed on Zn1-xCrxTe covering the energy range 1-7 cm-1 in fields up to 20 T at T = 1.2 K. The static magnetic field was oriented along the (100), (110) and (111) crystallographic axes of the sample. Pronounced absorption lines for intra-chromium transitions have been observed for these different orientations, revealing a strong anisotropy due to a static Jahn-Teller distortion. The measured low energy level structure of the Cr++ ion can be described by a cubic crystal field model including this distortion of the Cr centers.
