32. MD is estimated from the distribution of the largest dimension of the minimum volume box containing the molecule rotated in its inertial frame, obtained from the atomistic MD simulation at 227°C described in the experimental and Supporting Information sections.

50. To compare the experimental and theoretical polarization values, a scaling factor was required and thus we have scaled the value at 190° C in Figure 3B to the experimental one, but otherwise no fitting has been performed.
