Unit of Raman intensity or normalization

[twozniak28]

Dear Developers,

I'd like to compare the absolute values of individual peaks Raman intensities between different materials. It's possible for non-resonant Raman in QE, since it provides intensities in (A/amu)^4. What is the unit of intensity in QERaman? Or how should I normalize them to make such comparisons?

Best regards,
Tomasz
