Plane view of dyed, banded mannitol spherulites with 0.5 wt % (a) DAM, (b) MB and (c) CSB in α- and δ-polymorphs of D-mannitol in horizontally polarized (double arrow) white light. (d) Scheme of a banded spherulite. The dotted arrows represent the radial growth directions from the dot in the center of the spherulite, the site of nucleation. The dotted circle is the growth front of the spherulite, with the tangential direction labeled as a double arrow.
