There are some peaks in imaginary part of dielectric function which correspond to transition on its band structure.

This should be roughly what you want. Just be extra careful when interpreting the results. Band combination actually means band-index combination here, eg. in case of bandcrossings in your electronic structure the band index is not what you would expect as band in fundamental sense.<br></p><p><br></p><p>Best regards</p><p>Pavel<br></p><p><br></p></body></html>
