Popis: International audience; The theoretical determination of excited-state structures remains an active field of research, as these data are hardly accessible by experimental approaches. In this contribution, we investigate excited-state geometries obtained with Time-Dependent Density Functional Theory, using both linear-response and, for the first time, corrected linear-response approaches of the Polarizable Continuum Model. Several chromophores representative of key dye families are used. In most cases, the corrected linear-response approach provides bond distances in between the gas and linear-response data, the latter model providing larger medium-induced structural changes than the corrected linear-response model. However, in a few cases, the solvation effects predicted by the two continuum approaches present opposite directions compared to the gas phase reference.
