Comments: The UV absorption spectrum of dichlorine trioxide, Cl2O3 has been recorded in the wavelength range 220-340 nm 
and at 223 K using a recently developed flash photolysis-kinetic UV absorption spectroscopy apparatus.
The spectrum obtained is smooth, and shows a peak at 267 nm, where sigma = 1.76 × 10-17 cm2 molecule-1(base e). Results 
are broadly consistent with previous determinations of the spectrum, although we report higher cross-sections in the long-wavelength 
tail of the absorption.
