In fullerenes, the dynamics, molecular motion, and order- disorder tra
nsition temperature T(c) are strongly affected by the applied pressure
. In this study, single-crystal C-13 NMR spectroscopy is used to study
fullerenes under hydrostatic pressure as a function of temperature (2
00-343 K). Information is obtained on the thermodynamic properties of
these materials, their phase behavior and their molecular dynamics.
