Smectic (from the Latin smecticus - "having the properties of soap" [1]). All of the smectic phases are layered, belonging to the symmetry group.
Smectic A phase[edit]
In the smectic-A phase each layer is a 2-dimensional liquid, having the symmetry in the Schoenflies notation. [2] [3]
Smectic B phase[edit]
Smectic C phase[edit]
The smectic-C phase has the monoclinic symmetry .
Smectic E phase[edit]
Smectic F phase[edit]
