2. Chirality - Wikipedia

   en.wikipedia.org/wiki/Chirality

   Chirality (/ kaɪˈrælɪti /) is a property of asymmetry important in several branches of science. The word chirality is derived from the Greek χείρ (kheir), "hand", a familiar chiral object. An object or a system is chiral if it is distinguishable from its mirror image; that is, it cannot be superposed (not to be confused with ...

3. Chirality (physics) - Wikipedia

   en.wikipedia.org/wiki/Chirality_(physics)

   Chirality (physics) A chiral phenomenon is one that is not identical to its mirror image (see the article on mathematical chirality). The spin of a particle may be used to define a handedness, or helicity, for that particle, which, in the case of a massless particle, is the same as chirality. A symmetry transformation between the two is called ...

4. Chirality (chemistry) - Wikipedia

   en.wikipedia.org/wiki/Chirality_(chemistry)

   Chirality (chemistry) Two enantiomers of a generic amino acid that are chiral. (S)-Alanine (left) and (R)-alanine (right) in zwitterionic form at neutral pH. In chemistry, a molecule or ion is called chiral (/ ˈkaɪrəl /) if it cannot be superposed on its mirror image by any combination of rotations, translations, and some conformational ...

5. Chiral media - Wikipedia

   en.wikipedia.org/wiki/Chiral_media

   Chiral media. Chirality with hands and two enantiomers of a generic amino acid. The direction of current flow and induced magnetic flux follow a "handness" relationship. The term chiral / ˈkaɪrəl / describes an object, especially a molecule, which has or produces a non-superposable mirror image of itself. In chemistry, such a molecule is ...

6. Chiral auxiliary - Wikipedia

   en.wikipedia.org/wiki/Chiral_auxiliary

   Chiral auxiliary. In stereochemistry, a chiral auxiliary is a stereogenic group or unit that is temporarily incorporated into an organic compound in order to control the stereochemical outcome of the synthesis. [1][2] The chirality present in the auxiliary can bias the stereoselectivity of one or more subsequent reactions.

7. Point groups in three dimensions - Wikipedia

   en.wikipedia.org/wiki/Point_groups_in_three...

   The conjugacy definition would also allow a mirror image of the structure, but this is not needed, the structure itself is achiral. For example, if a symmetry group contains a 3-fold axis of rotation, it contains rotations in two opposite directions. (The structure is chiral for 11 pairs of space groups with a screw axis.)
