Abstract:
The microwave spectrum of sulfuryl fluoride, SO2F2, has been reinvestigated. The spectra of the S32 and S34 species in natural abundance have been analyzed, and the structure has been determined with the aid of the S34 isotope shift. The correction for zero-point vibration was shown to be small. The structural parameters are: rSO=1.405±0.003 A, rSF=1.530±0.003 A, & lt;OSO=123°58′±12′, and & lt;FSF=96°7′±10′. The molecular dipole moment is 1.110±0.015 Debye units. A number of satellite lines were observed and assigned to excited vibrational states. Some anomalies in the measured rotational constants for the excited states have been interpreted in terms of a Coriolis-type interaction between the fundamentals ν4(A1) and ν5(A2). From an analysis of this interaction the frequency of the hitherto unobserved ν4(A1) fundamental was found to be 388±15 cm—1.
