Supplementary Material
1. Previous determinations of ClOOCl absorption cross sections
2. Previous determinations of ClOOCl absorption cross sections post Pope et al. (2007)
3. Spectra of ClOOCl and possible spectral impurities
Figure S1 – Previous determinations of ClOOCl absorption cross sections [1-15]
Figure S2 – Previous determinations of ClOOCl absorption cross sections measured in
the last six years [1-3, 5-8]
Figure S3 – Spectra of ClOOCl and possible spectral impurities
Figure S3 shows the recommended absorption cross sections of ClOOCl together with other
possible spectral impurities which are generated in the production of ClOOCl. This study
generated ClOOCl by the photolysis of Cl2 in Cl2/O3 mixtures. Product impurities generated
in the reaction include OClO and Cl2O3. The spectra of ClOOCl, Cl2, O3, OClO, and Cl2O3
are given in figure S3. All spectra are from the JPL evaluation [16], apart from the ClOOCl
spectrum which is provided by this study.
