Hard X‐ray photon‐in photon‐out techniques are targeted at applications where the sample environment cannot be freely chosen. The resultant X‐ray emission spectra are influenced by the chemical environments of the atoms involved. If high‐resolution measurements are possible, the chemical effects in the X‐ray emission spectra can provide information about the chemical states, complementary to that offered by other X‐ray spectroscopies. X‐ray emission is classified into six categories for convenience: X‐ray diagram lines, X‐ray valence‐band emission, radiative Auger effect, resonant X‐ray emission, Compton scattering, and X‐ray Raman scattering. After a brief description of the history of research on these types of emission, the chemical effects that they reveal and related topics, including high‐resolution absorption measurements and the static structure factor, are reviewed. An overview of the instrumentation employed in both laboratories and synchrotron radiation (SR) facilities is also given.

We report recent observations of resonant inelastic X-ray scattering (RIXS) at the cerium L3-edge of CePO4, CeO2, and Ce3+ ion in aqueous solution. The intensity of the emission spectrum, including the dispersive Raman below the edge and the emerging nondispersive fluorescence above the edge, was recorded with a solid-state detector with low-energy resolution and a WDX detector with modestly high-energy resolution. The yield of the emission was used to monitor the cerium L3-edge X-ray absorption near edge structures (XANES) in a constant initial state (CIS) mode as the photon energy sweeps across the cerium L3-edge. The CIS XANES is compared with the XANES recorded using the nondispersive fluorescence yield, Lα, in a constant final state (CFI) mode. It is found that the Raman yield dominates the total emission in the pre-edge region and diminishes rapidly at threshold. The RIXS of Ce3+ in aqueous solution exhibits similar behavior as CePO4. The post-whiteline RIXS intensity of CePO4 exhibits a correlation with excitation energy. CeO2 also exhibits a less intense whiteline in CIS XANES compared with the XANES detected with normal fluorescence. The implications of these observations with improved instrumental resolution are noted.
