Question

what do you mean by d-d transition? ​

Answer 1

Explanation:

d-d Transitions

d-d Transitions In a d–d transition, an electron in a d orbital on the metal is excited by a photon to another d orbital of higher energy. In complexes of the transition metals, the d orbitals do not all have the same energy. In centrosymmetric complexes, d-d transitions are forbidden by the Laporte rule.
