Induced infrared absorption of molecular hydrogen in solid C60
We report on the observation of induced infrared absorption in a molecular species trapped within a C60 lattice. Infrared spectra for interstitial H2 show distinct rotational and translational side-bands superimposed on the H2's highly redshifted (54 cm-1) fundamental vibrational mode. Data indicate that the hydrogen is rotating almost completely freely while at the same time undergoing localized three-dimensional translational motion within the "box" formed by the C60 molecules.
