Title: Vibrational spectroscopy of sulfur hexafluoride attached to helium clusters
Abstract: We have built an apparatus capable of attaching a molecule to a liquid-helium cluster and obtaining its infrared spectrum. Clusters made of a few thousand atoms and containing an ${\mathrm{SF}}_{6}$ molecule show two absorptions located at 945.8 and 946.1 ${\mathrm{cm}}^{\mathrm{\ensuremath{-}}1}$ which indicate that the guest molecule is located near the surface of the cluster. If the cluster contains two ${\mathrm{SF}}_{6}$ molecules, the spectrum obtained is that of a slightly perturbed ${\mathrm{SF}}_{6}$ dimer.
