The far-infrared in-plane reflectivity of the organic superconductor -(BEDT-TTF)2I3 is measured down to frequencies of 10 cm-1; the optical conductivity is obtained by a Kramers-Kronig procedure. In the superconducting state an energy gap opens at 25 cm-1 which corresponds to in agreement with moderate coupling. Even well below K a considerable absorption remains for . We discuss different posibilities to explain this behaviour.
