OCCUPIED AND UNOCCUPIED ELECTRONIC STATES OF SOLID C70 WITH COMPARISON TO C60

The distribution of the valence and conduction band electronic states of solid C70 have been studied with synchrotron radiation photoemission and inverse photoemission. The results show 16 features in the valence band and 10 in the conduction band. The s- and p-character of these states is identified, with those closest to the Fermi level being attributed to p-pi-derived levels. Comparison to results for C60 shows differences due to reduced molecular symmetry and configurational disorder of the solid.
