    laporte rule is dominant

    See in complexes there is d-d transition so it is laporte forbidden

    Why tetrahedral is more intense than octahedral.

    eduncle-logo-app

    Because there is laporte relaxation in tetrahedral. You will know this once you study molecular orbital diagram of tetrahedral geometry

    here charge transfer transactiona are fully allowed so most intense

    eduncle-logo-app

    then spin allowed and and laporte partially allowed (p-d mixing)

    eduncle-logo-app

    so you can compair thesw values given in the table for different compounds and can compair the intensity for a series of complex compounds

    got it?

    Dear aswin,we compare spin allowed,spin forbidden,laporte allowed and laporte forbidden transitions by considering their absorption band....

    eduncle-logo-app

    Spin allowed transition gives most intense absorption band while spin forbidden the least....
