A coupled cluster protocol rooted in damped response theory is presented for computing Resonant Inelastic X-Ray Scattering spectra of molecules in gas-phase. Working equations are reported for both linear (i.e., equation-of-motion) and non-linear<br>parametrizations of the coupled-cluster wavefunction response. A simple scheme to<br>compute non-resonant X-ray emission spectra is also proposed. Illustrative results are<br>presented for water.
