摘要：

Raman scattering is used to study the thermal decomposition of photochemically produced polymeric C-60 films. Under the experimental conditions, a steady state monomer population is maintained through a competition between: (a) the photoattachment of monomers to other monomers and higher oligomers (e.g. dimers, trimers) driven by the Raman laser and (b) the thermal scission of the intermolecular C-C bonds. The rate for thermal dissociation of these bonds is found to follow an Arrhenius-type behavior with an activation energy E(a)=1.25 eV.
