Vibrational Spectra of Peroxydisulfuryl Difluoride S₂O₆F₂ and the Halogen Derivatives FOSO₂F and ClOSO₂F

Abstract

Vibrational spectra of the halogenfluorosulfates FOSO2F and ClOSO2F are recorded and Cs symmetry is suggested for the molecules. For peroxydisulfuryl difluoride a staggered non-planar configuration with C2 symmetry is indicated by the polarized Raman spectra.

Synthesis and structural characterization of fluorosulfate derivatives of silver(II)

“…After heating for 2 h at +130 °C and removal of all excess fluorine, both F0S02F and S206F2 were identified by their vibrational spectra. 20 The residual solid had no IR bands due to the S03F groups. Silver analysis: caled for AgF2, 73.95; found, 74.09.…”

The system fluorosulfuric acid (HSO3F) and bis(fluorosulfuryl)peroxide (S2O6F2) — a solution study

“…1. A comparison with the previously reported Raman spectra for HS03F (15) and S2O6F2 (16) as well as with a re-recorded spectrum on freshly distilled S2O6F2 allows the following conclusions: (i) The solution spectrum is in first approximation a composite spectrum of the two major components. (ii) The relatively strong, polarized vibrational bands of S206F2 are unperturbed and are clearly recognizable, while some of the weaker bands are not observed.…”

“…The vibrational spectra of the individual compounds are well known (15)(16)(17); (ii) NMR spectroscopy of both 'H and 19F nuclei; (iii) ESR spectroscopy of the system, to detect the onset of the formation of S03F' radicals and their persistence in HS03F. Again, the ESR spectrum of the S03F radical has been reported (14).…”

Unimolecular Decomposition of F2SO3- Calculation by Reduced Kassel Integral in Factorized Form

“…The Kassel parameter Sk was calculated as in reference [3], by means of the frequencies of the molecule [6], using the approximation Sk = 5eff + l, where Seff is applied to those internal coordinates which contribute to the overcoming of the threshold energy, these coordinates in general being oscillators and internal rotors.…”
