COMMENTS: Discharge flow tube reactor coupled to a to a multipass absorption cell and a diode array spectrometer (spectral resolution ∼1.2 nm)

The transient CI2O2 molecule was produced by using the gas-phase reaction CIO + CIO + M → Cl2O2 + M, and three independent CIO radical source reactions, CI + O3, CI + CI2O, and CI + OCIO were used

The ClO reference spectrum was quantified using an absorption cross section of 4.35×10-18 cm2 molecule-1 at 253.7 nm from
