abstract = {Plastic crystals are a promising candidate for solid state
ionic conductors. In this work, quasielastic neutron
scattering is employed to investigate the center of mass
diffusive motions in two types of plastic crystalline cyclic
alcohols: cyclohexanol and cyclooctanol. Two separate
motions are observed which are attributed to long-range
translational diffusion (α-process) and cage rattling (fast
β-process). Residence times and diffusion coefficients are
calculated for both processes, along with the confinement
distances for the cage rattling. In addition, a binary
mixture of these two materials is measured to understand how
the dynamics change when a second type of molecule is added
to the matrix. It is observed that, upon the addition of the
larger cyclooctanol molecules into the cyclohexanol
solution, the cage size decreases, which causes a decrease
in the observed diffusion rates for both the α- and fast
β-processes.},
