Abstract

High resolution infrared emission spectra of hot MgF₂ in the 700 to 1300 cm-1 region have been recorded. The molecules were generated by heating solid MgF₂ to 1675 °C. Four vibrational bands were rotationally analyzed yielding band origins and rotational constants. Observed bands are: 001-000 (Σu+ - Σg+), 01¹1 - 01¹0 (Πg - Πu), 02²1 (f parity) - 02²0 (f parity) (Δu - Δg), and 03³1 - 03³0 (Φg - Φu). High level ab initio calculations were essential in making assignments and in helping to fit the data. The Δ_u - Δ_g band was only observed for f-parity because the e-parity is significantly perturbed by l-resonance.
