The rotation structure of the nu1 + nu2 - nu3, 2nu1 - nu3, 2nu1, 3nu1, 2nu1 + nu3 and 3nu1 + nu3 overtone and combination bands of BrNO were examined at high resolution (.005 - .01 cm-1) using Fourier Transform Spectroscopy. Over 4900 spectral lines were recorded for the two isotopomers 79BrNO and 81BrNO. The rotational and quartic distortion terms, inertia defects and asymmetry parameters were determined for the (200), (300), (001), (200), (301) and (110) vibrational levels. The first-order vibration-rotation interaction terms were also determined.
