dear aakansha
the molecule which have an inversion center called as centrosymmetric complex .
and laporte rule only applies to the centrosymmetric complexes due to its nature and propoerty .
The Laporte rule is a spectroscopic selection rule that only applies to centrosymmetric molecules (those with an inversion centre) and atoms. ... Allowed transitions in such molecules must involve a change in parity, either g → u or u → g.
so, for that reason , the d-d transition forbidden for some molecule
hope it clears
