Notizen:
The pure rotational Raman spectrum of selenium trioxide monomer in the vapour phase at 410 K has been obtained and analysed for the first time. The following rotational constants and bond lengths were obtained: \documentclass{article}\pagestyle{empty}\begin{document}$$ \begin{array}{l} B_{\rm 0} {\rm = 0}{\rm .246\,60} \pm {\rm 0}{\rm .000\,05 cm}^{ - 1} \\ 10^{\rm 8} D_J {\rm = 3}{\rm .9} \pm {\rm 0}{\rm .04 cm}^{ - 1} \\ r_{\rm 0} {\rm = 168}{\rm .78} \pm {\rm 0}{\rm .02 pm} \\ \end{array} $$\end{document} This is the first spectroscopic determination of r0 in SeO3. The precision of r0 is significantly greater than the value of ra = 169±1 pm obtained from an earlier electron diffraction study.
