Questions on diatomic spectroscopy

  1. Jan 1, 2012 #1
    I've been looking at spectra from diatomic molecules. If I know the temperature of the material I'm looking at and I know which transition I want to look at how can I calculate what the observed flux (in Jansky) should be?
    Also, what can I calculate from observed FWHM?

    You need to solve the radiative transfer equation---in particular, finding the Einstein Coefficients

    The width of lines tells you many things concerning the cause of Line Broadening

    I have the Einstein coefficients and I know the relative population of states, but how do I use these to calculate a flux?
