Abstract
The action of $AgF_{2}$ on $S_{4}N_{4}$ in $CCl_{4}$ produces a gaseous compound, $NSF_{3}$, whose structure has been in some doubt. A pure sample was prepared. Fragments in the mass spectrum show that the molecular structure is probably $\begin{array}{lll}&F\\N-S&F\\&F\end{array}$ as most recently claimed by Glemser. The microwave spectrum was studied in the region 8,000 to 60,000 me with a conventional Stark modulated spectrograph. The spectrum has the simplicity and first order Stark effects characteristic of a symmetric top. From lines assigned to the normal and also to the $^{34}S$ and $^{15}N$ species occuring in natural abundance, the following set of structural parameters was obtained: d(S--N) = 1.416 {\AA}, d(S--F) = 1.552 {\AA}, and $<FSF = 94^{\circ} 2^{\prime}$. The above structure is thus confirmed.
