TL;DR: In this article, it was shown that true absorption coefficients can be obtained by eliminating the violent fluctuations in intensity with frequency by broadening the rotational lines with a non-absorbing foreign gas and eliminating the error due to the intensity variation of the envelope by extrapolating the apparent integrated absorption coefficient divided by the partial pressure to zero partial pressure of the absorbing gas.

TL;DR: The influence of spectrometer slit widths upon the shapes of some vibrational absorption bands has been examined in this article, and the relative significance of extinction coefficients and integrated intensities for quantitative work has been considered, and some general conclusions have been drawn about the difficulties of applying the convenient procedures previously worked out by ramsay for determining the true band intensities.
