The sodium ions located in the 12-membered ring main channel (with Q〓〓0.2 MHz) of zeolite omega are fully hydrated and so mobile to average out the 〓H-〓Na dipolar interaction, while those in the gmelinite cage (Q〓=2.3 MHz) are less hydrated and closely bonded to the lattice oxygen.

We proposed that the non-adiabatic passage at zero-crossings of quadrupole splitting would not lead to the great loss of the spin locking signals, and the second-order quadrupolar interaction had significant effects on triple-quantum coherences, which was responsible for the fast decay of the signals; the both experiments and numerical simulations supported this point of view.
另外，在该谱仪上还进行了四极核钠-23的自旋锁定效率的研究；从含时Shr〓dinger方程出发，提出了一个更为确切的四极分裂过零处的绝热通过判据，并指出四极分裂过零处的非绝热通过不会导致锁定信号的快速消失，四极相互作用的二阶项对三量子相干的影响不能忽略，它是引起锁定信号快速消失的原因；实验和数字模拟的结果证实了这个理论。

quadrupole：四极
所以我们得不到一个偶极运动,实际上得到的是一个四极(Quadrupole)运动:两个质量之间的空间发生改变,但其中心保持不变. 由於四极振荡可以使时空产生波动,同样的引力波也可在一对悬浮的质量上产生同样的四极振荡.
