Kβ x-ray emission spectroscopy (XES) is a spectroscopic technique that provides detailed electronic structure information about transition metal species. XES is complementary to x-ray absorption spectroscopy (XAS) in that it probes the occupied valence orbitals of transition metal systems with eV resolution, revealing information about metal spin state, ligand identity, and intra-ligand bonding. Moreover, XES can be coupled to XAS in a technique called high energy resolution fluorescence detected (HERFD) XAS, resulting in improved selectivity and edge resolution and allowing new insight on pre-edge transitions. In recent years, these techniques have found increasing applications across a broad range of disciplines and have been applied to everything from fuel cell materials to enzyme intermediates. The applications of these methods will be even further increased with the upcoming CHESS upgrade (CHESS-U), which will include a beamline dedicated to photon-in photon-out spectroscopy and will enable data collection on chemical reactions under operando conditions.
Our Workshop on X-ray Emission Spectroscopic Methods immediately follows the CHESS Users' Meeting and will provide an introduction to these techniques through both lecture and hands-on components. We will cover a variety of topics, including an overview of x-ray emission methods and their information content, experiment design, data acquisition and processing, and how DFT calculations can be used to predict and interpret experimental results. Current applications of these methods will also be highlighted. Afterward, participants will be able to bring their own samples to measure XES and/or HERFD XAS spectra at CHESS C-line
