  Spectroscopy experiments are routinely used to characterize the behavior of
strongly correlated systems. An in-depth understanding of the different
spectral features is thus essential. Here, we show that the spectrum of the
multiorbital Hubbard model exhibits unique Hund \ms{bands} that occur at
energies given only by the Hund coupling $J_\mathrm{H}$, as distinct from the
Hubbard satellites following the interaction $U$. We focus on experimentally
relevant single-particle and optical spectra that we calculate for a model
related to iron chalcogenide ladders. The calculations are performed via the
density-matrix renormalization group and Lanczos methods. The generality of the
implications is verified by considering a generic multiorbital model within
dynamical mean-field theory.
