THE SUBMILLIMETER SPECTRUM OF $Br_{2}O$

Abstract

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.
