The rotational spectrum and molecular parameters of BrO in the 2Π{3}/{2} state
Abstract
The ν = 0 and 1 rotational spectrum of BrO in the 2Π{3}/{2} state has been observed in selected regions between 60 and 400 GHz. The precision of previously measured parameters and the quality of the fit has been improved. In addition, the centrifugal distortion constant, D02, the effective Λ-doubling constant, qeff, the perpendicular quadrupole coupling constant, eqQ2, and a linear combination of the magnetic hyperfine constant, b, and nuclear spin-rotation constant, Crs, have been measured for the first time. The values of ωe and ωexe derived from the mechanical constants are in good agreement with very recent optical data.
