摘要：

Infrared-absorption studies of thin fullerene films as a function of temperature reveal a splitting of an absorption line at 245 +/- 3 K. Another absorption line narrows and its frequency shifts without splitting. These observations support earlier neutron- and x-ray-diffraction findings of an orientational phase transformation at 250 K in bulk samples. We provide an explanation based on an accepted crystal structure of C60.
