Recent developments in quantum chemical calculations of X-ray absorption spectra are reviewed, focusing on the use of time-dependent density functional theory to study core excitations.Abstract:
Recent advances in X-ray sources have led to a renaissance in spectroscopic techniques in the X-ray region. These techniques that involve the excitation of core electrons can provide an atom specific probe of electronic structure and provide powerful analytical tools that are used in many fields of research. Theoretical calculations can often play an important role in the analysis and interpretation of experimental spectra. In this perspective, we review recent developments in quantum chemical calculations of X-ray absorption spectra, focusing on the use of time-dependent density functional theory to study core excitations. The practical application of these calculations is illustrated with examples drawn from surface science and bioinorganic chemistry, and the application of these methods to study X-ray emission spectroscopy is explored.read more

Excited-state calculations with TD-DFT: from benchmarks to simulations in complex environments
TL;DR: This perspective aims to provide to non-specialists a flavour of recent trends in the field of simulations of excited states in "realistic" situations and to define an average TD-DFT accuracy in reproducing excitation energies when a conventional approach is used.

TL;DR: No single functional stands out as the most accurate for all aspects, but B3LYP yields the smallest mean absolute deviation, and M06-2X could be a valuable compromise for excited-states as it reproduces the 0-0 energies and also gives reasonable band shapes.
