 note = {This work presents a resonance Raman study of polyyne molecules (linear carbon chains) encapsulated inside single-wall carbon nanotubes using many different laser lines. A strong enhancement of the polyyne Raman features is observed around 2.1 eV, and this result is ascribed to dark electronic transitions of the linear carbon chains that can be observed when they are trapped inside a carbon nanotube. The huge observed energy splitting between bright and dark excited states is ascribed to strong Coulomb effects in this strictly onedimensional system.},
