Results of my close collaboration with Professor Mildred S. Dresselhaus and Professor Gene Dresselhaus on graphene and carbon nanotubes are overviewed. From the â¼200 publications we coauthored between 1991 and 2017, here we mainly discuss the established facts of resonance Raman spectroscopy of graphene and carbon nanotubes. To highlight some of the specific current problems of Raman spectroscopy, the title of each section is given as a question regarding an aspect of Raman spectroscopy, which can also be useful for understanding Raman spectroscopy of other low-dimensional materials. Instead of attempting to provide a detailed account of each fact, an extensive reference list is provided for the reader to obtain the current understanding of specific problems. We conclude by providing future prospects for Raman spectroscopy studies of nanotubes and 2D materials.
