Both, experimental and theoretical investigation are made of frequency‐modulated optical spectrum of Nb. The experimental spectra are measured in the range of light energy from 1 to 6 eV. The theoretical studies are performed in the framework of density functional formalism using the linearized hybridized KKR (LHKKR) method for self‐consistent calculations of band structure and wave functions. A reasonable coincidence between theoretical and experimental results is obtained.
