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 
regards
