Deuteron NMR Quadrupolar echo techniques are used to study slow molecular motions in solids. QE was used to investigate the molecular dynamics in complex systems. QE experiments were performed on host urea d-4 in two different urea inclusion compounds. Rotation rates around the CO bond-axis of urea-d4 in the UICs were determined as a function of temperature by matching QE simulations with the experiments. From this data activation energies were calculated.
