Raman spectroscopy is one of the most extensively employed methods for the characterization of carbon nanotubes. In this review article, an overview about Raman spectroscopy as a tool for the characterization of functionalized single‐walled carbon nanotubes (SWCNTs) is given. First, the relevant Raman modes in SWCNTs are introduced. Then, in a phenomenological approach, the effects that are observed for the individual modes in the Raman spectra are compiled and discussed. It is shown that special care has to be taken in order to separate the effects of functionalization, which are specific to a subset of the SWCNTs (metallic/semiconducting or diameter dependent), from changes in sample morphology or doping effects.
