    • 13 the relaxation at 120-160 °C seems to be related to the existence of residual water (or solvent). Therefore, aPAN without solvent shows only one relaxation at 70-110 °C, and a single-phase model looks most appropriate.

    • Even without distribution of CN side-group directions, the CSA pattern of Figure 7f is not symmetric, although each of the three subpatterns, shown by dotted lines, is symmetric. This is because the splitting for the downfield peaks is 17 ppm while that for upfield peaks is 34 ppm.
