Cyclotron resonance experiments in tellurium carried out over a wide and continuous range of microwave frequencies are described and analyzed; the influence of temperature and of the orientation of the magnetic field with respect to the crystallographic axes received particular attention. All the results are consistent with a $\overrightarrow{\mathrm{k}}·\overrightarrow{\mathrm{p}}$ perturbation model of the valence band structure. We determined the parameters of this model and find a quantitative agreement between theory and experiments.
