Figure 3.67 Polarized optical micrograph of a doubly banded spherulite in the chiral polymer poly(R-3-hydroxybutyrate). Two closely spaced extinction bands are separated by a wider light region the crystal strncture is orthorhombic and the indicatrix is an ehipsoid with two optic axes. Close inspection of the vertical arms of the Maltese cross reveals dark bands crossing the light regions from left to right, indicating that the twist is left handed. Scale bar is 25 mm.
