Abstract:
The rotational spectra of <sup>79</sup>Br<sub>2</sub>O, <sup>79</sup>BrO<sup>81</sup>Br, and <sup>81</sup>Br<sub>2</sub>O in their ground vibrational states as well as <sup>79</sup>BrO<sup>81</sup>Br in its v<sub>2</sub> = 1 state have been studied in selected regions between 90 and 523 GHz.
