Plastic Crystal
Subject: Physics | Topics:

Plastic crystal is a crystal composed regarding weakly interacting molecules that have any orientational or conformational degree of freedom. The name plastic crystal is the term for the mechanical actual softness of such stages of development: they resemble waxes and are easily deformed. If the internal degree of freedom is molecular rotation, the name rotor phase is usually used. Typical examples are the modifications Methane i and Ethane i.
