Abstract
\maketitle High resolution infrared emission spectra of hot BeF$_2$in the 800--2500 cm$^{-1}$ region have been rotationally analyzed. The $\nu_3$ fundamental band, $\nu_1 + \nu_2$, $\nu_1 + \nu_3$ and $2\nu_2 + \nu_3$ combination bands, and more than 15 hot bands were assigned. The $\nu_1$ ($\sigma_g$), $\nu_2$ ($\pi_u$) and $\nu_3$ ($\sigma_u$) frequencies were directly obtained by fitting several hot bands and combination bands together. A complete analysis of all the bands is in progress and will be presented. High level ab initio calculations have been performed for the MgF$_2$ molecule to predict its vibration-rotation spectrum. An infrared emission spectrum of MgF$_2$ was recorded and will be assigned with the aid of ab initio calculations.
