OSTI ID:10180977
The temperature-pressure phase diagrams of solid C{sub 60} and C{sub 70} have been determined and compared. A significant finding is the large influence of interstitial species and of the pressure transmitting medium on the orientational ordering processes. The pressure results reveal different, nearly degenerate configurations in both solids, which are believed to be due to hindered molecular rotations by interstitial species, and possibly different stacking modes in C{sub 70}.
