This distinction depends not on the orientation of the molecules (parallel or perpendicular to the radial direction) but to the orientation of the major refractive index of the molecule relative to the radial vector. The spherulite polarity depends on the constituent molecules, but it can also change with temperature.
This distinction hinges on the orientation of the molecule relative to the radial vector, rather than its alignment along a specific axis. The spherulite polarity is influenced by the molecular composition, and this relationship can be sensitive to temperature changes.
