A Study of the Reaction between C10 and NO₂ Using Matrix Isolation FTIR Spectroscopy and UV-Visible Spectroscopy

Summary

The products of the reaction between C1O and NO₂ have been investigated by photolysing flowing mixtures of Cl₂, C1₂O, NO₂ and N₂ with blacklamps (310–400nrn):

$$ \begin{array}{*{20}c} {\text{C10 + NO}_\text{2} + \text{M}} \hfill & { - > } \hfill & {\text{C10NO}_\text{2} \, + \,\text{M}} \hfill & {\text{(1a)}} \hfill \\ {} \hfill & { - > } \hfill & {\text{isomers}\, + \,\text{M}} \hfill & {\text{(1b)}} \hfill \\ \end{array} $$

The yields R₁ = [C1ONO₂]_ir/ [C1O], R₂= [C1ONO₂]_ir/ [NO₂], R₃ = [NO₂]/ [C1O] and R₄ = [C1ONO₂]_ir/ [C1ONO₂]_UV at 298K and a total pressure of 22 torr are (1.0±0.2), (1.0±0.3), (1.0±0.3) and (0.9±0.3) respectively. No kinetic or spectroscopic evidence was found for the formation of isomer by reaction (1) over the temperature range 253K–298K.
