A plastic crystal (or the rotor phase) is a state of matter whose almost-spherical molecules are located on crystalline lattice points, but have a degree of rotational disorder. Plastic crystals exist over a narrow temperature range; the temperature being sufficiently high so as to overcome any rotational energy barriers, but sufficiently low so as not to disrupt the lattice structure.
