Step: 121

The determination algorithm is based on the fact that one can divide the groups of points possible with molecules according to the type of the available axes of rotation into different types from point groups. The point groups of linear and cubic molecules are characterised by their high symmetry and are as such by view of the molecules to be detected immediately. By cubic symmetry one understands with the fact that the symmetry characteristics are concerning the three directions in space equal. E.g. the following geometrical things possess cubic symmetry:
