HUND’s Multiplicity Rule

This rule states, "that the pairing of electrons in degenerate orbitals of a particular sub-shell does not take place until all the orbitals of the sub-shell are singly occupied and the singly occupied orbitals must have the electrons with parallel spin".

  1. Definition of spin Multiplicity Rule
    According to spin Multiplicity Rule " transition between states of different multiplicity, S, are forbidden.
    It is a selection rule for electronic transition in complexes. And another selection Rule is Laporte Selection Rule. Which you read in next page of website www.chemistrynotesinfo.blogspot.com
