The resonance Raman intensity and optical absorption and emission of isolated single wall carbon nanotubes (SWNTs) are calculated by using electron-photon and electron-phonon matrix element calculations made by our groups. Single and double resonance Raman intensities of graphite and SWNTs are calculated in which the relative intensity of Raman spectra to one another is now possible compared with experiment as a function of nanotube diameter and chirality or as a function of excitation laser energy. The calculated results also show (1) optical intensity different between type 1 and type 2 SWNTs, (2) electron recombination rate for a photo-electron for each phonon branch, which are in good agreement with fast optics experiments.
