High-resolution stimulated Raman spectroscopy and analysis of the ν

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.
