\maketitle

The rotational spectra of the three main isotopic species of Br$_2$O have been studied in the submillimeter region. The combination of a relatively large $A$ rotational constant along with small values for $B$ and $C$ give rise to transitions involving a large range of $J$ and $K_a$ quantum numbers in the observed spectral region. Precise rotational and centrifugal distortion constants have been determined. Quadrupole splittings are large and can be observed even for $J > 90$. The spectrum, molecular structure, harmonic force field, and quadrupole coupling will be discussed.
