✦ Synopsis
The absolute UV cross section of BrO at 338.1 +O.l nm, the peak of the (7,0) band of the A('fI)+X('II) transition, was measured at 298+2 and 223&4 K to be (1.71+0.14) x lo-" and (2.21+0.16)~ lo-"cm', respectively, using the techniqueof flash photolysis-ultraviolet absorption. The spectral resolution for these measurements was 0.18 nm. The absorption spectra of BrO m the wavelength range 3 12-385 nm were measured at 298 f 2 and 223 i 4 K usmg a tlow tube reactor coupled to a diode array spectrometer. Using the (7.0) band cross sectlons, the absorption cross sections in the above wavelength range were calculated.
