Individual tubular graphite cones (TGCs) are characterized using Raman spectroscopy atroom temperature. A split G band at 1569–1587 cmÿ1 is directly observed from the root tothe tip of TGCs without requiring surface electromagnetic and chemical enhancementeffects. The G band can be deconvoluted into two Lorentzian peaks at 1571 ± 2 and1584 ± 3 cmÿ1, which may be attributed to the resonance enhancement of a single chiralityexcitation in the innermost tubes and all constituent tubes of the TGCs, respectively.Results suggest that the splitting of G band can be envisaged as a fingerprint for monochiralityof tubular carbon nanomaterials.
