First-Principles Simulation of Soft X-Ray Spectroscopy

• Soft x-ray spectroscopy represents a category of instrumental techniques to effectively probe the electronic and chemical structure of molecules, surfaces, and a variety of complexes by core excitations or de-excitations. The basic computational methods, based on the density functional theory, for different absorption and emission processes are reviewed in this paper. Special attention has been paid to the practical implementations and applications of different methods. Details on the simulations of commonly used K-edge x-ray photoelectron, absorption, and emission spectra for a wide range of illustrative examples including molecules, fullerenes, carbon nanotubes, graphenes and DNA, are provided.
