Abstract

The ν₁+ν₃ combination band of uranium hexafluoride (UF₆) is targeted to perform analytical enrichment measurements using laser absorption spectroscopy. A high performance widely tunable EC-QCL sources emitting radiation at 7.74 μm (1291 cm^-1) is employed as an UF₆-LAS optical source to measure the unresolved rotational-vibrational spectral structure of several tens of wavenumbers (cm^-1). A preliminary spectroscopic measurement based on a direct laser absorption spectroscopy of methane (CH₄) as an appropriate UF₆ analyte simulant, was demonstrated.
