We used infrared and Raman spectroscopy to investigate single crystals of the compound C60(C5H12)0.88(C7H8)0.05. We observed the signatures of the individual components C60 and pentane in the infrared spectrum with minimal changes when compared to solvent-free solid or solution spectra. The corresponding Raman spectrum shows that while the molecular C60 frequencies remain unchanged, there are some additional lines, probably due to symmetry effects of the solid state. We conclude that the material is a true clathrate with no electronic interaction between the constituents. Unlike the infrared spectrum pentane lines are not observed in Raman spectra.
