Publisher:Ohio State University
Pressure broadening of spectral lines can cause fine details in the absorption spectra of gases to be lost. As the pressure is decreased the details are observed but the line shape typically changes from a Lorentz shape to the Voigt shape. It is shown that, provided the physical conditions of the sample are known, the line intensity, position and Lorentz width can be determined by spectral curve fitting for a wide variety at Voigt shaped lines. The technique of Pierluissi et al. (1) was used to calculate the absorption coefficients of the lines.
