But I still don't undersdand where the Planck constant comes in... I understand that there are quantum numbers (n) and that there are many energy levels between n=1 and n=2. But what is the difference between the hyperfine levels? Is it the Planck constant h? Is there a possible configuration for any multiple of h? I'm missing some linear function. For example: ground state is X*h then, what happens if 1*h is added to the system? When to hyperfine levels change? when orbitals? when shells? | |
