The equilibriumhas been studied between 275°and 363°K. Third‐law calculations lead to Δ H ° 298 (1) = ‐11.50 ±0.17 kcal/mol, from which\documentclass{article}\pagestyle{empty}\begin{document}$$ \begin{array}{l} \Delta H_{{\rm f}298}^ \circ ({\rm BrNO},g) = 19.52 \pm 0.24\,{\rm kcal}/{\rm mol} \\ D_0^ \circ ({\rm Br - NO}) = 27.90 \pm 0.30\,{\rm kcal}/{\rm mol} \\ \end{array} $$\end{document}Absorption bands of BrNO in the ultraviolet with e (γ max = 215 nm) = 1.84±0.17 × 10 4 1/mol·cm, and in the red with e (γ max = 708 nm) = 7.7±1.9 1/mol·cm at 298°K have been investigated. The rate of formation of BrNO has also been measured between 275°and 363°K.
