摘要：

A rotationally resolved infrared spectrum has been obtained for SF6 molecules captured inside of helium clusters of approximately 4000 atoms. The spectrum is interpreted in terms of a spherical top Hamiltonian, although the resulting rotational constant is considerably smaller than that of free SF6. This can be attributed to the interaction between the molecule and the surrounding helium liquid. The results indicate that the SF6 is located inside the helium cluster and a fit to the spectrum yields a rotational temperatures for the perturbed SF6 of 0.37 +/- 0.05 K.
