ClOO + hv -> ClO + O

"Johnston et al. [779] measured the absorption cross sections of the ClOO
radical using a molecular modulation technique which required interpretation of
a complex kinetic scheme.  More recently, Mauldin et al. [1047] reported ross
section measurements in the range from 220 to 280 nm, and Baer et al. [81] from
240 to 300 nm.  These two studies are in very good agreement, yielding cross
section values which are more than twice as large as the older Johnston et al.
values.  The recommended cross sections are listed in Table 26, and are taken
from the work of Mauldin et al."
