Abstract
Raman investigations of C70 films in the 14–370-K range show significant changes across the orientational phase transitions around 270 and 330 K. Seven of the Raman modes of C70 soften smoothly across the transitions, the magnitude of the decrease in frequencies being in the range of 2-5 cm−1. Linewidths of the bands increase in the transition region over and above the anharmonic contributions.
