▎ 摘　　要

We calculated the polarized Raman spectra (PRS) and angle-resolved polarized Raman intensities (APRIs) of graphene nanoribbons with edges terminated by functional groups C=O and C-O-C, respectively, based on first-principles calculations. The exist results of the hydrogen saturated edges are recalculated for comparison. Our results show that the edge structures could be efficiently identified by the PRS and APRI. The APRI can also identify the orientation of the graphene nanoribbons.
