Most of the features exhibited by canonical glass-formers can also be found in systems with a high-degree of translational order. In addition to the well-known orientationally disordered phases (plastic phases) in which translational order remains while the orientation of the molecules is lost, given rise to the glassy crystals, some low-temperature “ordered” phases have recently appeared to display the key features of glasses. Examples as the monoclinic low temperature phases of CBrnCl4-n molecules (n= 0, 1, 2) or the low-temperature phases of some adamantane derivatives, have recently emerged. In these cases disorder originates from the different occupancies of some atoms in different sites. Here we propose to carry out a neutron study on the dynamic processes taking place in 1-F-adamantane (C10H15F) recently evidenced by dielectric spectroscopy.
