Abstract
We have made a Raman study of low-pressure polymerized and photopolymerized C-60 films, polymerized in different ways, but otherwise initially identic al. Although the structures developing in the films during polymerization a re initially very similar, an analysis of characteristic features in the Ra man spectra shows that photopolymerized material forms a more complex polym eric structure when the polymerization approaches saturation. We suggest th at this complex structure contains branched polymeric chains and in particu lar that a mode near 1454 cm(-1) in photopolymerized C-60 is characteristic for this type of structure.
