Abstract:
The far-infrared transmission of polycrystalline C60 and C70 compacts has been measured from 3 to 330 cm-1 as a function of temperature. Both intrinsic and impurity-induced absorption bands are identified in these samples. The low temperature phase of C60 is observed to have two infrared active translational modes at 40.9 and 54.7 cm-1. Samples of C60 exposed to air before cooling to low temperatures contain several additional infrared bands which have been identified with adsorbed H2O vapor. A large isotope shift is observed for some of the bands when H2O is replaced by D2O, consistent with rotational or librational behavior. For C70 one strong intrinsic band is centered at 21 cm-1 and four much weaker bands occur at 28, 32, 52, and 64 cm-1. When doped with H2O vapor, C70 also produces several strong H2O impurity bands, some of which show isotopic shifts. The temperature dependence of five intramolecular C70 modes in the frequency range from 200 to 330 cm-1 is also reported.
