Cr-SmC = solid to the SmC phase transition.

SmC-SmA = SmC to the SmA phase transition.

Cr-SmA = solid to the SmA phase transition.

SmA-N = SmA to the N phase transition.

SmA-I = SmA to the isotropic phase transition.

N-I = nematic to the isotropic phase transition.

ΔS/R = normalized entropy of transition.
