Complete infrared and Raman spectral measurements extend the earlier work of Cross, Roberts, Goggin and Woodward on $SF5Cl1$ and of Eggers, Wright and Robinson on $CF3SF52$ All of the active fundamentals for both molecules have been observed, and reassignments in the case of $SF5Cl$ are made on the basis of the selection rules for a $C4v$ molecule. The data and analysis of the spectrum of $CF3SF5$ strongly support the low barrier model previously suggested on the basis of infrared measurements $alone.2$
