The elusive connection between dynamics and local structure in supercooled liquids is an important piece of the puzzle in the unsolved problem of the glass transition. The Johari-Goldstein beta relaxation, ubiquitous in glass-forming liquids, exhibits mean properties that are strongly correlated to the long-time alpha dynamics. However, the former comprises simpler, more localized motion, and thus has perhaps a more straightforward connection to structure.
