(Damped) Response Methods for x-ray absorption spectroscopy, photoionization cross sections and other “exotic” molecular spectroscopies

An account of recent work on damped response methodologies based on either coupled cluster wave function ansatzes or time-dependent density functional theory to compute x-ray Near-Edge Absorption Fine Structures [1,2,3], photoionization cross-sections [5] as well as other “exotic” response properties of atoms and molecules in resonant and non-resonant frequency regions [3,4,6,7] will be presented.
