Abstract
We represent results of IR reflectivity and transmission measurements in the spectral range from 50 to 5000 cm−1 for crystallographic {111} and {100} planes of C60 single crystals between 80 K and 460 K. The spectra turned out to be highly anisotropic due to differences in geometric resonances. The geometries used allowed detailed simultaneous investigation of the four infrared activeF 1u fundamental modes together with some weak silent modes and the whole set of second- and third-order combination modes from an analysis of the reflection-transmission response. Photopolymerization is observed on the surface of the crystals after illumination in argon atmosphere. The orientational phase transition at 260 K is accompanied by a dramatic jump in the line widths within a fraction of a degree. This result is explained by a broadening mechanism due to collisions with librons and paralibrons for the low temperature phase and for the high temperature phase, respectively.
