X-ray Absorption Spectroscopy (XAS) is one of the core competencies of synchrotron science. With sensitivity both to chemical state and to the local configurational environment, the unique view of matter offered by XAS has become an indispensable tool for a broad range of scientific disciplines. With the advent of high-flux, third-generation synchrotron sources, new experiments probing the structure of inner shell electrons are now possible. In this talk, I will discuss recent developments in crystal-based spectrometry. Among the new capabilities are XAS with energy below the level of the core-hole lifetime, X-ray emission spectroscopy providing a complementary view of electromic and chemical state, X-ray Raman spectroscopy which allows access to low energy absorption edges and dipole forbidden transitions, and XAS measured at ultra-low absorber concentration. Special emphasis will be placed on instrumentation under development for beamlines at NSLS-II.
