Abstract
We present a microscopic analysis of the quantum solvation structures of para-H2 around the OCS molecule when embedded in low temperature 4He droplets. The structures of clusters containing M=5 and 6 para-H2 molecules are compared with corresponding structures for M=1 (OCS-H2 complex) and M=17 (a full solvation shell), as well as with the clusters in the absence of helium. We find that the helium has negligible effect on the structures for the small and large OCS(H2) M clusters, but that it modifies the cluster structure for M=6. We discuss implications of these resugts for the onset of superfluidity in the solvating hydrogen shell and for spectroscopic measurements.
