Single walled carbon nanotubes (SWNT) potential applications include using functionalized nanotubes for drug delivery and in the development of new electronic materials. A reliable method of characterizing SWNTs would increase general applicabity and fully understand SWNT functionalization would be useful in SWNT synthesis quality control. To address the inherent difficulty in characterizing the functionalization, we report using a number of spectroscopic methods to characterize SWNT functionalization. Functionalizing SWNTs and their model compounds, and the use of IR, NMR and Raman to characterize the products will be discussed.
