The chiral structure of single-walled carbon nanotubes (SWNTs) and the edge structure of graphene nanoribbons (GNRs) play an important role in determining their electronic and phonon structures. Spectroscopic methods, which require simple sample preparation and cause minimal sample damage, are the most commonly utilized techniques for determining the structures of SWNTs and graphene. In this review the current status of various spectroscopic methods are presented in detail, including resonance Raman, photoluminescence (PL), and Rayleigh scattering spectroscopies, for determination of the chiral structure of individual SWNTs and the edge structure of isolated graphene, especially of graphene nanoribbons. The different photophysical processes involved in each spectroscopic method are reviewed to achieve a comprehensive understanding of the electronic and phonon properties of SWNTs and graphene. The advantages and limitations of each spectroscopic method as well as the challenges in this area are discussed.
单壁碳纳米管（SWNTs）的手性结构和石墨烯纳米带（GNRs）的边缘结构在决定它们的电子和声子结构方面起着重要作用。光谱方法是最常用的确定 SWNTs 和石墨烯结构的技术，因为这些方法需要的样品制备简单，对样品的损伤最小。在这篇综述中，详细介绍了各种光谱方法的现状，包括共振拉曼、光致发光（PL）和瑞利散射光谱法，这些方法用于确定单个 SWNTs 的手性结构和孤立石墨烯的边缘结构，特别是石墨烯纳米带的边缘结构。本文综述了每种光谱方法中涉及的不同光物理过程，以全面了解 SWNTs 和石墨烯的电子和声子特性。讨论了每种光谱方法的优缺点以及该领域的挑战。
