For XANES, previous basis-set testing suggests that the demands of core-level absorption spectroscopy are not much different from those of valence TD-DFT calculations, meaning that double-ζ basis sets are often sufficient. This contrasts the situation for correlated wave function models, where an improved treatment of the core functions is imperative, 113,114 and there has been some suggestion that basis-set effects are more significant in TD-DFT calculations of XES spectra. Our results suggest this is not the case, however.
