Dear Quantum Espresso User, First of all I would like to express my sincere gratitude to all who are associated with this forum . I am a Quantum Espresso user.Currently I am doing some calculation based on turbo_davidson. I have a query regarding to Quantum Espresso. During my calculation I have used "Norm-conserving" pseudopotential. In that case can I explain the intensity of absorption spectra in terms of Thomas–Reiche–Kuhn sum rule? If this law is not valid in case non-local potential,then may I know, to explain the intensity which formula can be used.
