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.
