| 图9 (a) MA0.6(d3)DMA0.4PbBr3的固体静态2H NMR谱，实验温度为150~300 K；(b) MA的模拟2H NMR谱.谱图模拟条件：MA发生双重旋转运动，θ值取54.7?，绕旋转轴Rc的旋转速率（Ω）从32 kHz变化到fast limit |
| Fig. 9 (a) Static solid state 2H NMR spectra of MA0.6(d3)DMA0.4PbBr3. The experimental temperatures range from 150 K to 300 K; (b) The simulated 2H NMR spectra of MA. Spectral simulation conditions: MA undergoes the double rotation. The angle between Rc and C-N axis is θ = 54.7?, and the rotation rates (Ω) range from 32 kHz to fast limit |
