N2 - The v = 1-0 band of BrO in the X2Π 3 2 spin state was measured using high-resolution Fourier transform absorption spectroscopy. One hundred and thirty transitions were assigned and analyzed to determine the band origins, rotational constants, and distortion constants for both 79BrO and 81BrO. The v = 1-0 band strength was determined to be 5.04 ± 0.80 cm-2 atm-1 using a Herman-Wallis type analysis. The A2Π-X2Π transition of BrO was measured in the region 285 to 355 nm simultaneously with the infrared measurements with a diode array spectrometer. UV absorption cross sections of the A2Π-X2Π transition were determined relative to the calculated IR intensities. The absorption cross section at the peak of the (7, 0) band at 338.5 nm is (1.4 ± 0.3) × 10-17 cm2 molecule-1 at 298 K.
