  We measured the optical signature of the charge density waves (CDWs) in the
multiband conductor TTF[Ni(dmit)2]2 by electronic Raman scattering. At low
energies, a hump develops below 60 K. This hump is associated to the amplitude
mode of the CDW with an energy around 9 meV. Raman symmetry-resolved
measurements show that the CDW amplitude mode is anisotropic and that the CDW
can be associated to the band nesting of Ni(dmit)2 chains.
