The Schoenflies (or Schönflies) notation, named after the German mathematician Arthur Moritz Schoenflies, is a notation primarily used to specify point groups in three dimensions. Because a point group alone is completely adequate to describe the symmetry of a molecule , the notation is often sufficient and commonly used for spectroscopy .
There are 3 types of dihedral symmetry in three dimensions, each shown below in 3 notations: Schönflies notation, Coxeter notation, and orbifold notation. Chiral. D n, [n,2] +, (22n) of order 2n – dihedral symmetry or para-n-gonal group (abstract group: Dih n).
Rotation about an axis through the origin by an angle θ. Rotation by θ = 360°/n for any positive integer n is denoted C n (from the Schoenflies notation for the group C n that it generates). The identity operation, also written C 1, is a special case of the rotation operator. The indirect (orientation-reversing) operations:
