Comments: The absolute UV cross section of BrO at 338.1 ± 0.1 nm was measured at 298±2 and 223±4 K to be (1.71±0.14) × 10-17 
and (2.21±0.16) × 10-17 cm2, respectively, using the technique of flash photolysis-ultraviolet absorption. The spectral resolution for these 
measurements was 0.18 nm. The absorption spectra of BrO in the wavelength range 312–385 nm were measured at 298±2 and 223±4 K 
using a flow tube reactor coupled to a diode array spectrometer. Using the (7,0) band cross sections, the absorption cross sections in the 
above wavelength range were calculated.
