This contribution addresses the solvent effects on the second-order nonlinear optical
responses of three representative anil derivatives, and in particular on their variations upon
switching between the enol-imine and keto-amine forms. The impact of solute-solvent
interactions is investigated by means of ab initio and DFT calculations in which solvent
effects are included through the polarizable continuum model. In addition, for one of the
compounds, Hyper-Rayleigh Scattering experiments and ab initio calculations are combined …
