| 图6 甲基发生内旋转时，(a) DMA离子的运动模型和(b) DMA氘代甲基的模拟2H NMR谱.谱图模拟条件：C-D键与C-N轴之间的夹角θ = 70?，运动速率达到fast limit |
| Fig. 6 (a) The motion model of DMA cation and (b) the simulated 2H NMR spectrum of CD3 in DMA when methyl groups undergo the intrinsic rotation along C-N bond. Simulation condition: the angle between C-D bond and C-N axis θ = 70?, and the rotation rate reaches fast limit |
