Molecular superfluidity within a small helium cluster. — •Slava Grebenev — MPI fur Stromungforschung, Bunsenstr. 10, D37973, Gottingen.

Infrared spectroscopic measurements off the OCS embedded in He droplets are reported. The spectra in 4He reveal good resolved rotational structure, when in 3He rather broad structurless band. This difference was attributed to different states of the droplets: superfluid for 4He and normal fluid for 3He. addition of 4He atoms to the 3He droplet revealed the superfluidity of the 4He cluster having only 100 atoms.
