Concept Introduction:
The number and nature of the symmetry elements of a given molecule are conveniently represented by its point groups and give rise to labels such as
These point groups belongs to the classes of C groups, D groups and special groups, the latter containing groups that has special symmetries, i.e. octahedral, tetrahedral and icosahedral.
A centrosymmetric molecule or ion contains a centre of symmetry and non-centrosymmetric molecule or ion does not contain a centre of symmetry.
