Can s oribtal electrons only drop to other s orbitals?

Click For Summary
SUMMARY

The discussion centers on the behavior of s orbital electrons during energy transitions. It is established that an electron in an s state (l = 0) can only transition to another s state if it drops in energy, but this is not allowed for dipole transitions. Instead, dipole transitions from s orbitals are permitted only to p orbitals (l = 1) due to the requirement of a change in the momentum quantum number (Δl = 1). The dipole operator's odd symmetry further restricts transitions, confirming that s to s transitions are not feasible.

Just a thought:

The momentum quantum number given for s states is l = 0. If an S state electron dropped in energy, and emitted a photon with l = 1, what would take place?


Am I correct that the electron could only drop to a lower l = 0 (an S state) orbital?
 
Physics news on Phys.org
Dipole transitions from s are only allowed to p orbitals.
 
Why can't a drop to s take place? I infer that a drop to p(l = 1) can take place because \Delta l = 1.
 
The dipole operator is odd, so it only gives overlap between states with odd and even symmetry.
