Point Group Theory

This site contains details of various symmetry point groups, their inter-relations and specific information regarding dipole-transition selection rules.

• Introduction and notes to symmetry operations and dipole transitions
• Categorisation of point groups crystal class (cubic, tetragonal etc.)
• Categorisation of point groups by unit cell
• General rules for products of irreducible representations
• Isomorphism and symmetry operation periodicity
• Stereographs for non-cubic crystallographic point groups
• 3D objects for crystallographic point groups
• Example molecules for some point groups
• Correlation tables
• Molecular symmetry test
• Some links.
• Some references for symmetry in physics and chemistry
