Abstract

The rotation structure of the $\nu_{1} + \nu_{2} - \nu_{3}, 2\nu_{1} - \nu_{3}, 2\nu_{1}, 3\nu_{1}, 2\nu_{1} + \nu_{3}$ and $3\nu_{1} + \nu_{3}$s 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 $^{79}BrNO$ and $^{81}BrNO$. 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.
