  We present a molecular dynamics study of the liquid and plastic crystalline
phases of CCl$_3$Br. We investigated the short-range orientational order using
a recently developed classification method and we found that both phases behave
in a very similar way. The only differences occur at very short molecular
separations, which are shown to be very rare. The rotational dynamics was
explored using time correlation functions of the molecular bonds. We found that
the relaxation dynamics corresponds to an isotropic diffusive mode for the
liquid phase, but departs from this behavior as the temperature is decreased
and the system transitions into the plastic phase.
