Selection Rules

  • #1

Main Question or Discussion Point

The selection rules state that:
Δl=±1
Δml=0,±1

I can't figure out a case where Δml=0 and Δl=±1, can anyone help by giving an example? Thanks.

E.g. emission of light by an excited hydrogen atom with the electron being in a p_z (m=0, l=1) to the s orbital (m=0, l=0).
