We report on a pump-probe study of CoMoCAT nanotube suspensions with
narrow chirality distribution. Visible pump pulses and a white light
continuum are used for resonant excitation of the strongest dipole
allowed E-22 subband exciton in the semiconducting (6, 5) tube and for
broadband probe of the resulting spectral transients between 1300 nm and
480 nm, respectively. Transient spectra show signatures of both
photobleaching (PB) and photoabsorption (PA) with practically identical
decay- but slightly different rise-times. The experiments reveal that
apparent variations of decay rates at different wavelengths do not
reflect dynamics of different relaxation processes but are a consequence
of the superposition of PB and blue-shifted PA response. (c) 2006
