Der Sättigungsdruck von NbBr5 und Tal5

Sublimation Pressure of NbBr₅, NbI₅, and TaI₅ The sublimation pressure of NbBr₅, NbI₅ and TaI₅ has been determined by a spectralphotometric method: . The vapour pressure of NbI_5,1 is equal to log \documentclass{article}\pagestyle{empty}\begin{document}$ {\rm P}\,{\rm = }\, - \frac{{4653}}{{\rm T}}\, + \,5.43 $\end{document}. All the pressure are given in atm. The melting point of NbI₅ is 673 ± 1 K.
