Lorentzian line shape profile

  1. Jul 2, 2012 #1

    I hope some one can help me with this one:

    I have a Lorentzian line profile

    L(√L) = 1 / ((√L - √0 )^2 + ([itex]\Gamma[/itex]2/4))

    for v = 0.

    For v [itex]\neq[/itex] 0 I have

    [itex]\int[/itex](1 / ((√L - √0 - kvz)^2 + ([itex]\Gamma[/itex]2/4)) * g(vz) dvz)

    I suppose the factor g(vz) dvz is a velocity factor, but how do I calculate it or where can I read more about the Lorentzian line shape profile with this velocity factor. I can only find descriptions about the Lorentzian without this velocity factor.

    Hope someone can give me a hint or an explanation to this as I do not understand it.

    Thanks :-)
