| 图11 (a) 基于MA运动模型Ⅲ（θ = 54.7˚，Ω = 3 000 kHz）和Ⅳ（θ = 54.7˚，Ω = 82 kHz）的拟合2H NMR谱（180.0 K）；(b) 180.0 K时，氘代MAPbCl3样品的实验2H NMR谱（黑色线）和拟合谱（灰色线）.该线型是由图(a)两个拟合2H NMR谱按比例叠加而来 |
| Fig.11 (a) Simulated solid state 2H NMR spectra (180.0 K) based on the motion model Ⅲ (θ = 54.7˚, Ω = 3 000 kHz) and Ⅳ (θ = 54.7˚, Ω = 82 kHz) of MA cation; (b) Experimental (black line) and simulated (gray line) solid state 2H NMR spectra of deuterated MAPbCl3 at 180.0 K. At this temperature, the spectra can be simulated by superimposing two curves in Fig. (a) proportionally |
