Extinction Coefficient

  1. Jun 13, 2014 #1
    I'm trying to calculate the extinction coefficient of air at 275 nm wavelength. Can someone help me do this? I can't seem to find enough variables in any equation I've been using to figure it out. Thank you

    What have you got so far? Do you have an experimental result that you are trying to match?

    Are you familiar with the Lorentz oscillator model? That won't fill in all the unknowns, but it could help you to constrain it somehow. You might try to look up the closest few absorption lines to the wavelength you are looking at, and maybe you obtain some rough estimates based on the distance in wavelength to the resonances and the transition probability.
