## 抄録

The resonant second-order (formula presented)-band Raman spectra of isolated single-wall carbon nanotubes (SWNTs) exhibit an interesting resonance phenomenon, whereby the (formula presented) band for some special (formula presented) isolated SWNTs exhibits a two-peak structure, while for most SWNTs, the (formula presented)-band profile is a single Lorentzian peak. The two-peak phenomenon is explained by combining the double-resonance Raman effect, originally introduced for graphite, with the singular electronic structure of SWNTs, which is unique for a given (formula presented) pair. Therefore, the (formula presented)-band profile is strongly dependent on the joint density of electronic states and provides useful information about the electronic structure and on the (formula presented) assignment for the specific SWNT that is in resonance with the laser.
