Pressure-dependent transmittance measurements on films of unoriented and oriented single-walled carbon nanotubes were carried out at room temperature in the midinfrared up to the visible frequency range. The optical transitions in the SWNTs show anomalies at around 2 GPa, which can be attributed to a structural phase transition. The shift to lower frequencies and broadening of the absorption bands with increasing pressure could be attributed to the structural deformation of the SWNTs. We found no indications for a pressure-induced dimensional crossover in the oriented SWNTs.
