The irreducible representation is a set of numbers that describe how a structure changes under the various symmetry operations. Applications are given in context of electronic and vibrational spectroscopy as well as chemical reactions following orbital symmetry rules. A square is in some sense “more symmetric” than When a molecule has the symmetry of a group \(\mathcal{G}\), this means that each member of the group commutes with the molecular Hamiltonian \[[\hat G_i,\hat H]=0 \quad i=1...h \label{8}\] where we now explicitly designate the group elements \(G_i\) as operators on wavefunctions. Once the properties are identified, the molecule is assigned its point group. Molecular Symmetry. When additional symmetry elements are present, Cn forms a proper subgroup of the complete symmetry point group. It conveys a sense of order.
