The initial structure was first optimized in vacuum, and then the resulting structure was used as a starting point for three geometry optimizations in the investigated solvents. The solvation effects were included using ddPCM. As the analytical forces are not yet supported in Psi4/ddX, we used the automatic numerical differentiation provided by Psi4 to carry out the optimizations. On the final four structures, we performed excited state calculations using ADC (2). The solvation effect on the excited states was included through a perturbative linear response correction . The results are reported in table . The ground state energy (Hartree-Fock) progressively decreases with an increasing dielectric constant of the environment. The first and third excited states are dark and are only slightly influenced by the different dielectric constants of the environment, whereas the second excited state is bright and undergoes the expected red-shift when going from a low polarity solvent to a high polarity solvent. The general trend is in agreement with experimental results , however, a quantitative agreement is missing mostly due to limitations of the continuum solvation models .
