Comments: Absorption spectra of gas-phase OClO in the 325-435 nm region (23000-31000 cm-1) have been measured at five atmospheric 
temperatures between 213 and 293 K with a spectral resolution of 1.0 cm-1 using Fourier-transform spectroscopy. Absolute absorption 
cross-sections of OClO at 293 K have been determined and were also used to scale the spectra at the lower temperatures to absolute cross-sections.
