Fig. 8 (a) The Gaussian distribution of the inclined angle, θ, in the double rotation model of DMA cation. The standard deviation is σθ0 is the initial value of θ; (b) The simulated 2H NMR spectra of CD3 in DMA using the model in (a). Spectral simulation conditions: θ0 = 54.7?, the rotation rate along the rotation axis Rc is 100 kHz; The 2σ values change from 0? to 20?
