Abstract

Pressure-induced molecular orientational ordering in single crystals of $C_{60}$ has been studied by Raman spectroscopy. The strongest intramolecular mode attributed to the double bond stretching "pentagonal pinch" vibration shows considerable softening across the transition around 3.5 kbar. The linewidths also increase considerably at higher pressures, indicating an orientational glassy state.
