Theoretical interpretation of the high-energy electro-absorption spectrum of crystalline fullerene
The microscopic model used previously for interpreting the low-energy electro-absorption (EA) spectrum of the fullerene crystal is applied to reproduce theoretically the corresponding signal at 4.5 eV, It is demonstrated that the spectral feature observed at that energy, in spite of its shape resembling that located at 3.7 eV and attributed to CT excitons, is in fact due to a Frenkel state, (C) 2002 Published by Elsevier Science B.V.
