Rotationally Resolved Spectroscopy of SF6in Liquid Helium Clusters: A Molecular Probe of Cluster Temperature
Abstract
A rotationally resolved infrared spectrum has been obtained for S${\mathrm{F}}_{6}$ 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 S${\mathrm{F}}_{6}$. This can be attributed to the interaction between the molecule and the surrounding helium liquid. The results indicate that the S${\mathrm{F}}_{6}$ is located inside the helium cluster and a fit to the spectrum yields a rotational temperatures for the perturbed S${\mathrm{F}}_{6}$ of $0.37\ifmmode\pm\else\textpm\fi{}0.05$ K.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
