Electronic interactions in multiorbital systems lead to non-trivial featuresin the optical spectrum. In iron superconductors the Drude weight is stronglysuppressed with hole-doping. We discuss why the common association of therenormalization of the Drude weight with that of the kinetic energy, used insingle band systems, does not hold in multi-orbital systems. This applies evenin a Fermi liquid description when each orbital is renormalized differently, asit happens in iron superconductors. We estimate the contribution of interbandtransitions at low energies. We show that this contribution is stronglyenhanced by interactions and dominates the coherent part of the spectral weightin hole-doped samples at frequencies currently used to determine the Drudeweight.
