The phonon structure in optical data can be inverted to obtain the transport electron‐phonon spectral density α 2 F tr (o). For more general electron‐boson exchange models we test the accuracy of using Allen's approximate relationship between spectral density and optical scattering rate instead of complete Eliashberg equation results. Both, s ‐wave and d‐wave superconducting gap symmetries are considered.
