18. The lamellar period of the linear paraffins in the orthorhombic crystalline state increases linearly with the number of carbon atoms as d(Å) = [1.94 ± 0.33] + [1.270 ± 0.001]n.
19. This assumption is perfectly legitimate here. As discussed below, the ionic groups are indeed arranged laterally according to a hexagonal lattice whose parameter (7.2 Å) is independent of the chain length.
20. The relative shift of the ionic sheets in the polar bilayers of SmY is impossible to measure experimentally by X-ray diffraction. It is also impossible to evaluate through molecular modeling by minimizing the electrostatic interactions because the electron density distribution in the ionic sheets is strongly dependent upon the relative shift.
