Abstract

Using the incoherent quasielastic neutron scattering technique, we have studied the molecular reorientations of 1-cyanoadamantane C 10 H 15 CN in its plastic phase. The measurements were done at eight temperatures from 256 K to 423 K using a powder sample. Multiple scattering effects were taken into account using a semianalytical method previously described in another paper. It is shown that molecular motions consist in reorientational jumps between twelve equilibrium positions equally spaced by 30° around the [100] directions of the lattice.
