Homework Help: Charge-to-mass ratio with Zeeman Effect

  1. Dec 12, 2009 #1
    1. The problem statement, all variables and given/known data
    I'm supposed to determine e/m using Zeeman effect.
    B=0.45 T
    Difference between two spectral lines is also known (0.649x10^10 Hz)

    2. Relevant equations
    Normal or anomalous Zeeman effect? How you know it?
    I'm guessing normal, so
    [tex]\Delta E = m_{l} \frac{e \hbar}{2m_{e}}B[/tex]

    [tex]\Delta E = h \Delta f[/tex]


    [tex]\frac{e}{m_{e}} = \frac{h \Delta f2m_{e}}{m_{l} \hbar B} [/tex]

    3. The attempt at a solution

    Well the attempt at solution is the equations I just wrote, are they right so far?

    But the problem is, how I get [itex]m_{l}[/itex]? I think it's [tex]2l+1[/tex], but how I get [itex]l[/itex] from the know data then?
