While a point group contains all of the symmetry operations that can be performed on a given molecule, it is not necessary to identify all of these operations to determine the molecule's overall point...While a point group contains all of the symmetry operations that can be performed on a given molecule, it is not necessary to identify all of these operations to determine the molecule's overall point group. If so, then there are n such C 2 axes, and the molecule is in the D set of point groups. If so, the molecule is either in the C nh or D nh set of point groups. If not, and if the molecule has n perpendicular C 2 axes, then it is part of the D n set of point groups.
