摘要：

By applying the Raman contour, quasielastic neutron scattering and NMR relaxation methods the reorientational correlation times of the NH3 groups and the ClO-4 ions in [Mg(NH3)6] (ClO4)2 were obtained. These times for the NH3 groups do not show any significant change in the phase transition region (139-154 K). The barrier to NH3 rotation is ≈500 cal/ mole and K. The ClO-4 ion reorientation, on the other hand, exists only in the high temperature phase. © 1979.
