Chirality
From Online Dictionary of Crystallography
Chiralité (Fr). Chiralität (Ge). Chiralità (It). 対掌性 (Ja). Хиральность (Ru). Quiralidad (Sp).
Chirality is the geometric property of a rigid object of being non-superposable on its mirror image. An object displaying chirality is called chiral; the opposite term is achiral.
