Finally, we analysed I EV (q) as an alternative to the solvent-solvent term I v (q) for including scattering from the local structure of the solvation shell and its excluded volume. We identified two different features of the I EV (q) term, arising from (1) the scattering from the contrast between the solvent and the hole left by the excluded volume, and (2) from the local structure in the solvent shell around the solute. We showed that, for analysis of difference scattering signals, e.g. from time-resolved experiments, the I EV (q) term is less affected by pertubations in the bulk solvent density that can manifest themselves when the overall extension of the solute is modified but the simulation cell is kept constant over both simulations.
