This document provides an overview of inelastic light scattering in carbon nanostructures from the micro to the nanoscale. It begins with a discussion of Raman spectroscopy and vibrational modes in sp2 carbons like nanotubes and graphene. It then reviews the development of carbon nanostructures from graphite to fullerenes to nanotubes to graphene. The rest of the document discusses techniques like tip-enhanced Raman spectroscopy that allow single-nanotube spectroscopy at the nanoscale. It also covers applications of carbon nanostructures in areas like bioengineering and discusses methods for characterizing structures and interactions.
