The use of neutron diffraction, neutron inelastic scattering, and optical spectroscopy to probe the nature of the medium-range order (MRO) in amorphous materials is discussed with reference to chalcogenides of GeSe/sub 2/, SiSe/sub 2/, and also P/sub 50/Se/sub 50/, and SiO/sub 2/ glasses. While none of these probes provides a unique determination of the MRO, the use of information obtained from the three techniques, supplemented by numerical calculations based on specific structural models, can provide a picture of the essential elements of glass structure. 5 refs., 4 figs.
