The molecular motions of Fullerene C60 and Fullerenes encaging H2 and D2 have been investigated in the low wavenumber region. The encaging Fullerenes offer the opportunity of investigating the spin selectivity of the para and ortho H2 species, so that a stronger nuclear spin polarization may be produced. In the present study we demonstrate that terahertz spectra can clearly distinguish between the pure and encaging Fullerenes. The presence of different absorbance peaks identified by THz spectra suggests that this tool has required sensitivity for detecting the spin isomers of H2 and D2 inside C60. Additionally, the increased number of observed peaks indicates that this method can detect the modes not visible in IR or Raman, yielding unique insight into uncharacterized host-guest interactions. Many of the states identified from THz spectra matches with theoretically predicted states of C60 including a number of degeneracies. These results will be discussed.
