This means that this representation corresponds to both x and y and should be included only once. IR activity is determined by the dipole moment and a mode will be active if the irreducible representation contains a linear part (x, y or z).

As was mentioned in the last chapter, there is no limit to the order of a representation; that is, it may consist of matrices of any size. Two modes have the same irreducible representation: A1. To take an easy example, the Square Planar Complexes.. starting with the sigma orbital of the ligands, the reducible representation of the sigma orbital is the total number of atoms that do not move under each operation.
