Using femtosecond pump probe spectroscopy with sub-20 fs resolution, we probe fundamental properties of the En exciton in (6,5) single walled carbon nanotubes, prepared by density gradient ultracentrifugation. From the initial photobleaching (PB) signal, measured faster than any relaxation process,...
