Raman spectra of graphene nanoribbons with zigzag and armchair edges are calculated within non-resonant Raman theory. Depending on the edge structure and polarization direction of the incident and scattered photon beam relative to the edge direction, a symmetry selection rule for the phonon type appears. These Raman selection rules will be useful for the identification of the edge structure of graphene nanoribbons.
本文运用非共振拉曼理论计算了锯齿形和扶手椅形边缘石墨烯纳米带的拉曼光谱。根据入射和散射光子束相对于边缘方向的边缘结构和偏振方向，出现了声子类型的对称选择规则。这些拉曼选择定则将有助于识别石墨烯纳米带的边缘结构。
