Benchmarking Core Excitations
High level quantum mechanical calculations produce a benchmark dataset of 1s core levels for organic molecules
The GW Green's function method has become a popular tool to compute valence excitations for a wide range of substances and materials. In this article, we test the GW method on X-ray photoelectron spectra. We present a benchmark study for 65 molecular 1s excitations. Our absolute and relative GW core-level binding energies agree within 0.3 and 0.2 eV with experiment, respectively. More information can be found in
