The sodium doublet refers to the spectral lines observed at 5890 Å and 5896 Å, which are a result of the transitions in sodium's quantum states. This phenomenon is primarily due to the hyperfine structure that further splits these lines into a quadruplet. The splitting occurs because of the interaction between the nuclear spin and the electronic spin in the 3p states of sodium. Understanding this requires a grasp of quantum mechanics and atomic structure principles.
PREREQUISITESStudents and professionals in physics, particularly those focusing on atomic and quantum physics, as well as anyone interested in the practical applications of sodium in lighting technologies.
Why only 2? Are you neglecting the spin-splitting in the 3p states?dextercioby said:
