    • However, there should be only a slight contribution of splay, at first the number of molecules in the cross section of the ribbons is smaller than in other polarization modulated smectic phases, secondly a splay with a ±90° change of the polar direction is also unlikely, as this should lead to the formation of a rectangular ribbon phase
