Abstract

High-resolution UF₆ absorption spectra at 16 μm have been obtained with the use of tunable diode lasers and a long-pathlength (~10³-m) sample cell. The frequencies of the <i>v</i>₃ Q-branch subband heads for both ²³⁸UF₆ and ²³⁵UF₆ have been determined, along with those for the (<i>v</i>₃ + <i>v</i>₆) − <i>v</i>₆ "hot-band" transition. Band contour studies have been carried out as a function of temperature, and comparisons are made with previous work.
