abstract = {UV/Vis absorption spectra of ClOOCl isolated in neon
matrices were measured in the wavelength range 220-400 nm.
The purity of the trapped samples was checked by infrared
and UV/Vis matrix spectroscopy as well as low-temperature
Raman spectroscopy. At wavelengths below 290 nm, the results
agree with the UV spectrum recently published by Pope et al.
[J. Phys. Chem. A, 2007, 111, 4322-4332]. However, the
observed absorption in the long wavelength tail of the
spectrum-relevant for polar stratospheric ozone loss-is
substantially higher than reported by Pope et al. Our
results suggest the existence of a ClOOCl electronic state
manifold leading to an absorption band similar to those of
the near UV spectrum of Cl(2). The differences to previous
studies can be accounted for quantitatively by contributions
to the reported absorption spectra caused by impurities. The
observed band in the long wavelength tail is supported by
several high-level ab initio calculations. However,
questions arise concerning absolute values of the ClOOCl
cross sections, an issue that needs to be revisited in
future studies. With calculated photolysis rates based on
our spectrum scaled to previous cross sections at the peak
absorption, the known polar catalytic ozone-destruction
cycles to a large extent account for the observed ozone
depletion in the spring polar stratosphere.},
