Figure shows 00ℓ spots for C31H64 crystals, further confirming the 'chains-flat' crystals exhibit lamellar layers with well-ordered end-to-end packing. Dorset and colleagues have noted the relative intensity of these spots as a marker of deviations from well-ordered lamellae in favor of nematic phases. These spots are notably mostly absent in the SAED patterns of C30H61OH in the 'chains-flat' orientation (Figure ).
