    It;s actually a quadruplet, as the hyperfine structure further splits each line in the 5890 and 5896 A in another 2.

    Why only 2? Are you neglecting the spin-splitting in the 3p states?

    A couple of clicks away from the Hyperphysics page I referenced is a really cool example of a sodium lamp! :rofl:
