Abstract
At high temperatures aluminum monohalides are easily produced in the gas phase by heating $AlX_{3}$ ($X=F$, $Cl$, $Br$, $I$) with Al. The high resolution infrared emission spectrum of AIF was measured with the McMath Fourier transform interferometer at Kitt Peak. The ro-vibrational emission spectrum of AICI was measured with the Bruker IFS 120 HR Fourier transform spectrometer at the University of Waterloo. About 500 lines of AIF and more than 2000 lines of AlCl were observed. These ro-vibrational transitions and pure rotational transitions form the literature were fit to a set of Dunham coefficients $Y_{ij}$. In the case of AlCl a set of mass-reduced Dunham coefficients $U_{ij}$ were also determined.
