The near U‐V photolysis of t ‐butyl nitrite has been studied over the temperature range 303–393 K. Under these conditions t ‐butyl nitrite was shown to be a very clean photochemical source of t ‐butoxy radicals. This allows a study of the decomposition of the t ‐butoxy radical to be made over this temperature range (3).Extrapolation of the rate constants k 3 to high pressure and combination with our previous thermal data give the results:\documentclass{article}\pagestyle{empty}\begin{document}$$k_3 (\infty)/{\rm s}^{{\rm - 1}} = 10^{14.04 \pm 0.37} \exp (- 7519 \pm 70.5/T)$$\end{document}
