For Argon, like Mercury, the quadratic background needed to be removed. To do that, the original Argon data was fit to a quadratic function. The original Argon data was then subtracted from the quadratic fit, to produce the Argon data without background.\\  After background was removed, quadratic functions were fit to the different peaks and dips to get distinct $E_n$ values. Just like Neon and Mercury, once these values were found, the measured spacings, ($\Delta E_{n}$), between the maxima and minima of the Franck-Hertz curve were plotted against the minimum order (n) of the peaks and dips and analyzed using a linear fit. (Figure 8)  Linear functions were fit to the $\Delta E_n$ data in order to determine an intercept at $n=0.5$. The actual value for Argon I (from NIST ASD data) is $11.54835392 $11.548  eV$ and another one that is close at $11.62359221 $11.624  eV$. It is possible for multiple energy states to be observed since the values are so close. This could be a potential explanation for some of the substructure seen in the Franck-Hertz curve for Argon.\\
