Nuclear Quadrupole Interactions as a Probe of Glass Molecular Structure

Abstract

125 Te absorption and 129 I emission Mössbauer spectroscopies have proved to be the methods of choice to probe chalcogen chemical order in condensed matter using nuclear quadrupole interactions. In chalcogenide glasses, the technique has been unusually rewarding in decoding both the elements of local atomic structures and those of the medium-range atomic structures.
