摘要：

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 SF6 molecule show two absorptions located at 945.8 and 946.1 cm-1 which indicate that the guest molecule is located near the surface of the cluster. If the cluster contains two SF6 molecules, the spectrum obtained is that of a slightly perturbed SF6 dimer.
