ქიმიის ტერმინთა განმარტებითი ლექსიკონი

State of matter in which the degree of molecular order is intermediate between the perfect three-dimensional, long-range positional and orientational order found in solid crystals and the absence of long-range order found in isotropic liquids, gases and amorphous solids.

Note 1: The term mesomorphic state has a more general meaning than liquid-crystal state, but the two are often used as synonyms.

Note 2: The term is used to describe orientationally disordered crystals, crystals with molecules in random conformations (i.e., conformationally disordered crystals), plastic crystals and liquid crystals.

Note 3: A compound which can exist in a mesomorphic state is usually called a

mesomorphic compound.

Note 4: A vitrified substance in the mesomorphic state is called a mesomorphic glass and is obtained, for example, by rapid quenching or by crosslinking.
