Abstract

In this chapter, we discuss the basic concepts of resonance Raman scattering and photoluminescence and how these optical spectroscopies are key for accessing the electronic states of condensed matter systems. In particular, we used carbon nanotubes as a model system for discussing how Raman spectroscopy and photoluminescence are powerful for determining with high resolution the energy of the confined electronic states. These techniques are among the most promising for advancing the science of nanomaterials because they are noninvasive, contactless, readily available, and allow one to characterize materials incorporated in devices.
