Homework Help: Zeeman effect pattern, Intensities?

    Im dong the zeeman effect for Mercury trasitions 3S1 --> 3P0/1/2 (Violet, Blue and Green lines).

    I've taken CCD pictures of all lines in a weak B field and with polaroid placed parallel and perpendicularly, and produced graphs of pixel value v column number (intensity v horizontal position).

    I cannot work out how to interpret the intensities. I've got the relative ratios from my data but they don't seem to be correct (well i don't know).

    And i cant explain why the Blue pattern is missing it's central peak, ie there should be 7 transitions for 3S1 -->3P1 but graph only shows 6

    http://www.breadnet.middlebury.edu/~PHManual/Photos/zeeman/fig4.gif [Broken]

    (From breadnet.middlebury.edu) a) is Blue pattern b) Green

    Can somebody point me on the right path?

    What would those 7 be; from which levels in 3S1 to which levels in 3P1?

    J=1 in both shells so mj = -J,0,+J = -1,0,+1

    Transitions,

    mj= 1 -> mj = 1 Delta mj=0
    mj= 0 -> mj = 0 Delta mj=0 <--This one is missing why?
    mj=-1 -> mj =-1 Delta mj=0
    mj= 1 -> mj =0 Delta mj=-1
    mj= 0 -> mj =-1 Delta mj=-1
    mj= 0 -> mj =1 Delta mj=1
    mj=-1 -> mj =0 Delta mj=1

    Thanks

    It is forbidden. See the very last paragraph of
