The effects of electrochemical redox doping on the electronic state of the nanotubes were investigated in an electrode potential window between –2 and +1.7 V vs. Ag-pseudoreference electrode. The bleaching of .DELTA.E11S and .DELTA.E22S optical transitions is traced for particular tubes, which allows a partial quantification of changes in the electronic density of states (DOS) caused by their filling with electrons or holes.
