The Laporte rule (law) applies to electric dipole transitions, so the operator has u symmetry (meaning ungerade, odd). p orbitals also have u symmetry, so the symmetry of the transition mome…

WebTherefore we see that l = l ′ , while allowed by the rules of addition of angular momentum (if l ≠ 0 ), is not allowed by parity conservation. (The rule for the integral of a product of three spherical harmonics is given in section A.2 .) So finally, for hydrogen, we have the following selection rules: Δ j = 0, ± 1, Δ m j = 0, ± 1 and ...
