Fundamental understanding of x-ray interactions with atoms and molecules provides a basis for applying x-ray methods to complex materials, such as structural determinations by x-ray diffraction and extended x-ray absorption fine structure. Compton scattering measurements of electron-momentum P distributions, and determinations of local chemical environments by x-ray interactions with atoms and molecules relevant to understanding elastic and inelastic scattering cross sections far from threshold and resonance and threshold phenomena in x-ray fluorescence. The ideas are discussed in the context of providing theoretical interpretations of experimental results and are topics of ongoing theoretical developments. We also discuss experimental methods of x-ray spectroscopy using solid-state and wavelength-dispersive spectrometers with excitation by tunable synchrotron radiation. The examples discussed are primarily from the authors' research. We did not attempt to provide a comprehensive review, but several recent review articles and research papers are referenced for further information. The ideas discussed are general and relevant to understanding fundamental studies and applications of x-ray scattering and fluorescence.
