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 v3 Q-branch subband heads for both 238UF6 and 235UF6 have been determined, along with those for the ( v3 + v6) – v6 “hot-band” transition. Band contour studies have been carried out as a function of temperature, and comparisons are made with previous work.
