摘要：

In the present investigation, we show that neutron-spin echo spectroscopy is perfectly suited for probing the molecular reorientations of orientationally disordered crystals. Our study confirms the existence of a dynamical crossover where molecular reorientational motions change in nature as already observed in previous NMR and Raman experiments and molecular dynamics simulation.
