Dear Karem,<br>
<br>
With turbo_lanczos.x you can compute an absorption spectrum. Then by looking at the spectrum, you choose a peak of interest, and its position would be your omeg.<br>

I'm studying the plasmonic properties of Borophene decorated with some metals. I'm using turbo_lanczos.x to calculate the absorption spectrum. I need to determine the parameter "omeg" which represent transition energy in Ry as mentioned on the </div>
