用准弹性和非弹性中子散射技术研究了方钠石Na_8 [AlSiO_4]_6（OH）_2中氢的动力学性质。数据进行了分析与跳跃模型的氢运动（OH重取向）。在295 K下，跃迁过程的特征时间为2.1 ps，局域振动频率（跃迁尝试频率）为17.4 THz。详细的分析表明，在（Na_4OH）_3+络合物阳离子的氢环境具有低于四面体对称性。
The dynamical properties of hydrogen in the sodalite Na8[AlSiO4]6 (OH)2 were investigated by quasielastic and inelastic neutron scattering techniques. The data were analyzed with a jump model for the hydrogen motion (OH reorientation). The characteristic time of the jump process is 2.1 ps at 295 K, the frequency of the local vibration (jump attempt frequency) is 17.4 THz. The detailed analysis shows that the hydrogen environment in the (Na4OH)3+ complex cation has lower than tetrahedral symmetry.
