The photochemistry of condensed films of OClO was examined with photofragment spectroscopy. Photolysis of multilayers of OClO on a polycrystalline Pt surface with 355 nm light yields predominantly atomic O, O 2 , atomic Cl, and ClO photofragments. We have measured the quantum yield for the Cl product channel to be 0.8±0.1, which is approximately 800 times higher than reported values for the non‐resonant gas‐phase photolysis of OClO. This result may have implications for stratospheric ozone chemistry.
