Abstract
Assignments of the $UF_{6}$ spectra described in the preceeding paper will be discussed. A total of 43 line frequencies and 110 frequency differences extending in J to P(77), Q(91), and R(67) has been used to fit seven spectroscopic constants. High-J data allowed the independent fitting of ($B\zeta)_{3}$ and hence of the rotational constants $B^\dag$ and $B_{U}$. The derived U-F bond length in the ground vibrational state is $r_{0} = 1.9962 \pm 0.0007$ \AA. The use of frequency differences as a supplement to absolutely-calibrated transition frequencies in fitting spectroscopic and molecular constants will be discussed.
