Solid-state 29 Si and 71 Ga NMR was used to study the synthetic gallosilicate Na 16 Ga 16 Si 24 O 80 ·16H 2 O (Ga–natrolite). It has been shown that Ga–natrolite contains mainly Si(GaO 4 ) 3 (SiO 4 ) and Si(GaO 4 ) 2 (SiO 4 ) 2 -structural units and has sufficiently ordered structure. Temperature dependence of the spin–lattice relaxation time T 1 of 71 Ga nuclei has also been studied using solid-state NMR. Spin–lattice relaxation of the 71 Ga was determined to be governed by the electric quadrupole interaction with the crystal electric field gradients modulated by translational motion of H 2 O molecules in the Ga–natrolite pores.

合成镓硅酸盐钠沸石的核磁共振研究

固态 29 Si 和 71 Ga NMR 用于研究合成镓硅酸盐 Na 16 Ga 16 Si 24 O 80 ·16H 2 O（Ga-natrolite）。已经表明，Ga-natrolite 主要包含Si(GaO 4 ) 3 (SiO 4 ) 和Si(GaO 4 ) 2 (SiO 4 ) 2 结构单元，并且具有足够有序的结构。71 Ga 原子核的自旋-晶格弛豫时间 T 1 的温度依赖性也已使用固态 NMR 进行了研究。71 Ga 的自旋-晶格弛豫受电四极与晶体电场梯度的相互作用控制，晶体电场梯度由 Ga-natrolite 孔中 H 2 O 分子的平移运动调制。
