A detailed study on the photoselective Raman response of p‐type intercalated single‐wall carbon nanotube (SWCNT) is presented. Here, we focus on the high doping region. The shift of the G‐line is used to monitor the doping level of the p‐type intercalated SWCNT using irontrichloride. Special emphasis is given on the changes in the dispersion of the D‐ and G′‐lines as a function of doping. For very high doping levels a decrease of the slope is observed.
