High-resolution stimulated Raman spectroscopy and analysis of the ν₂, ν₅ and 2ν₆ bands of ³⁴SF₆

Abstract

The ν₂, ν₅ and 2ν ₆ regions of ³⁴SF₆ have been studied by stimulated Raman spectroscopy. We used an isotopically pure sample of ³⁴SF₆. A detailed analysis of the ν₂ and ν₅ fundamentals has been performed with the HTDS program suite (http://www.u-bourgogne.fr/LPUB/hTDS.html) dedicated to octahedral XY₆ molecules. We also present a preliminary analysis of the 2ν ₆ band for both ³²SF₆ and ³⁴SF₆. Finally, we give the ³²S−³⁴S isotopic shifts for all the SF₆ fundamentals.
