Dear Said,
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.

Kind regards,

Karel
