I'v got a series of F.O. related questions.. If you could help, would be
appreciated.
Question for today.. 
(1) Does hydroxyl absorption affect all wavelengths linearly?
    (ie: I'm trying to make a graph, which shows absortion in dB 
     attenuation  due to the 'water bands' in F.O. So I need to
     know if all IR wavelengths are attenuated the same amount of dB's
     by the OH- and other impurities.)
    Although most of the books I have on the subject say the attenuation
    is linear, I suspect it is not.. it cant be..  Different wavelengths
     have hence different 'energy values' of light (planks constant) and so
     each wavelength must cause a different amount of atomic resonation
    (which is what causes the absorption.)
