your question is too general for anyone here to answer in detail - interpreting optical properties of solids can easily be a one-semester course for 3rd-year physics students or so. The central quantity is the frequency-dependent permittivity calculated in WIEN using Eq. (14) of Ambrosch-Draxl et al. 2006 article (doi: 10.1016/j.cpc.2006.03.005 ) and its interband part, Eq. (16), carries information about transitions between individual electronic bands in the material. So, you can make conclusions about the band structure from optical measurements.<br>

Dear Wien Users ,how to interpret the graphs of the optical properties <span class=""><br>
( The imaginary part of the complex dielectric and real part , the<br>
reflectivity R( w ),the refractive index n( w ),the absorption coefficients,<br>
the electron energy-loss function L( w )).<br>

Please, could you help me?<br>

Best wishes.<br>
