Schematic illustration of the relative orientation of the tilted lipid tails in the three phases comprised by the L_β′ phase. Yellow cylinders represent the in-plane projections of the lipid tails. The phases differ in the azimuthal angle (φ) as shown. For the L_βF and the L_βI phase with φ = 0° (A) and φ = 30° (C), respectively, there is a reflection symmetry about the tilt direction. In L_βL phase (B) the reflection symmetry about the tilt direction is broken. Adapted from Smith et al.⁴²
