Selection rules for Hydrogen

  1. Oct 16, 2015 #1
    Good afternoon,

    Does the selection rules have a condition on [itex]\Delta n[/itex] ? I have not found a website or a book that show transitions between [itex]2S_{1/2}[/itex] and [itex]2P_{3/2}[/itex], that's why I was wondering if [itex]\Delta n = 0[/itex], with respect to the other selection rules, are allowed transitions.

    Thank you for your answers.

    ##\Delta n = 0## is not a restriction for a transition to occur, in fact when one takes spin-orbit effect into account the levels of constant ##n## split further and transitions among them can happen.
