Dear Karem, 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.

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 reference of turboTDDFT calculations and the Input file. Does it depend on the structure that I'm working with? and how can I find its value exactly? Kazem Zhour PhD student University of Santiago de compostela
