Notes: Abstract The photodissociation coefficient, J NO2 of NO2 in the atmosphere was calculated at 235 and 298 K using the measured temperature dependences of the absorption cross-sections and quantum yields. These calculations gave a ratio J NO2(298 K)/J NO2(235 K)=1.155±0.010 which is only weakly dependent on altitude, surface albedo and solar zenith angle.

Notes: The reactions of O3 with CH3ONO and C2H5ONO were studied using infrared absorption spectroscopy in a static reactor at temperatures between 298 and 352K. Both reactions followed simple second-order kinetics forming the corresponding nitrate: The rate coefficients are given by \documentclass{article}\pagestyle{empty}\begin{document}$$\log _{10} {\rm}k_1 ({\rm cm}^{\rm 3} /{\rm molc} \cdot {\rm sec}) = (- 12.17 \pm 0.23) - (\frac{{5315 \pm 172}}{{2.303{\rm}T}})$$\end{document} \documentclass{article}\pagestyle{empty}\begin{document}$$\log _{10} {\rm}k_2 ({\rm cm}^{\rm 3} /{\rm molc} \cdot {\rm sec}) = (- 15.50 \pm 0.16) - (\frac{{2351 \pm 116}}{{2.303{\rm}T}})$$\end{document}.
