| Abstract | The rotational spectra of the fluorosulfate (FSO3 center dot) molecular radical in its vibronic ground state were measured in the millimeter-wave region and analyzed in detail using the matrix elements of the rotational, fine, and hyperfine Hamiltonian terms. The analysis of the assigned transition frequencies made it possible to derive very precise values of the rotational, centrifugal distortion and fine structure constants and to confirm the C-3v molecular symmetry of the vibronic ground state unambiguously. In addition, an effective parameter of the "A(1)-A(2) splitting" was determined. The rotational transitions of the FSO3 center dot free radical were observed, identified, and analyzed for the first time. |
