Many methods for analysis of the atomic structure of glasses have been developed, from both experimental and theoretical perspectives. For instance, diffraction experiments using high-energy X-ray and neutron beams can be used to experimentally determine the interatomic distances of the atoms of interest. Solid-state nuclear magnetic resonance (NMR) and Raman spectroscopy can be used to evaluate local coordination structures such as coordination number and symmetry. X-ray photo-electron spectroscopy and X-ray absorption fine-structure (XAFS) provide access to the valence and bonding states of atoms. These methods have advantages and disadvantages in terms of experimental setup and sample preparation. Hence, multiple structural analyses using a combination of several methods are often required to approach the true structure of the glass. However, despite progress in terms of both analytical methodology and hardware, accurate modeling of glasses in multicomponent systems remains a difficult problem.
