Abstract

We experimentally quantify the Raman scattering from individual carbyne chains confined in double-walled carbon nanotubes. We find that the resonant differential Raman cross section of confined carbyne is on the order of 10<sup>-22</sup> cm<sup>2</sup> sr<sup>-1</sup> per atom, making it the strongest Raman scatterer ever reported.
