Inelastic light scattering by self-formed linear-chain aggregates of carbon atoms in gold island films

The study of the optical response of gold island films revealed an intense line in the light scattering spectrum near 2100 cm$^{-1}$. Some possible reasons for the appearance of this line are considered. Comparison of the results obtained for films obtained by various technologies, light scattering spectra on other types of samples, as well as comparison with the results of other authors allow us to interpret the line as the result of inelastic light scattering by one-dimensional carbon chains.
