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.

3〓Na MAS及〓Na二维四极章动实验的研究表明，在NaΩ分子筛中存在两类不同水合状态的钠离子：一类处于12-圆环主孔道中(四极作用常数Qcc＝0.2MHz)，另一类处于菱钾沸石笼里(Qcc＝2.3MHz)。

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。

In this work, the N〓-broaden halfwidths of the pure rotation and v〓 band of water vapor have been calculated by using QFT theory, which involves the three intermolecular interactions: short range, dipole-quadrupole, and quadrupole-quadrupole (denoted as QFT〓).
