The work smectic comes from the Greek for soap (). All of the smectic phases are layered, belonging to the symmetry group.
Smectic A phase
In the smectic-A phase each layer is a 2-dimensional liquid, having the symmetry in the Schoenflies notation.
Smectic B phase
Smectic C phase
The smectic-C phase has the monoclinic symmetry .
