This paper explores the possibilities offered by coupling C nanomanipulation with resonance Raman excitation profile approaches. We apply this method to nanostructures produced by AFM nanomanipulation. The experimental demonstration is made on the interaction between two single-wall carbon nanotubes, one semiconducting and the other metallic. The measurement is analyzed and discussed in terms of resonance shifts and broadening of the electronic transition. This paper focuses on the example of the interaction between one (18,0) metallic SWCNT with one (11,9) semiconductor SWCNT. Our experimental setup allows to measure the evolution of resonance width from 75 cm(-1) to 100 cm(-1) for an isolated carbon nanotube (CNT), to more than 200 cm(-1) for interacting CNTs.
