Single-walled carbon nanotubes can be described by an (n,m) naming convention that specifies different angles for rolling up a graphene sheet into a tube. The properties of the tubes change for each (n,m) combination, and Bachilo et al. (p. 2361) have identified a signature for the semiconducting nanotubes based on their absorption, fluorescence, and Raman spectra. The authors pose questions about current one-electron theories of nanotube-excited states and also present an analytical method that may aid in the understanding of nanotube synthesis.
