Description	Ionic liquids like butylmethylimidazolium tetrafluoroborate are shown to be an advantageous electrolyte for the study of charge transfer reactions at carbon nanostructures. Hence, single-walled carbon nanotubes (SWCNT) and fullerene peapods (C60@SWCNT) were charged electrochemically in this electrolyte. Compared to traditional electrolyte solutions, this medium offers broader window of electrochemical potentials to be applied. The used ionic liquid has also favorable optical properties for in-situ Vis-NIR and Raman spectroelectrochemistry of nanocarbons. Electrochemistry of both nanotubes and peapods is dominated by their capacitive double-layer charging. In-situ measured Vis-NIR spectra of nanotubes and peapods demonstrate reversible bleaching of the transitions between Van Hove singularities. At high anodic potentials, new optical transitions were activated. They were assigned to electron transfer within partly filled valence band.
