The complete relativistic calculation of electron states in heavy b. c. c. d‐metals is performed by the Green's function method to interpret the experimental optical absorption data. The interband optical conductivity is computed in the framework of the single‐particle density matrix formalism taking into account the dipole transition matrix elements. It is shown that consequent relativistic approach permits to interpret reliably the experimental results for the main band of the optical absorption. The effect of the spin‐orbit interaction on the absorption in the infrared region is investigated.
