A single sheet of sp2-hybridized carbon atoms, called graphene, is presently the most widely studied material in the scientific community. Following a brief introduction of graphene and its unique properties, I will present two popular methods for preparing graphene for spectroscopic studies. In carbon science, spectroscopy has played a dominant role in unraveling several fundamental properties of nanostructured carbons like fullerenes and carbon nanotubes. Drawing from these spectroscopic studies, the effective roles of Raman and UV-vis spectroscopy in elucidating the vibration and electronic properties of graphene will be discussed.
