Excitation energies of pyrene were determined with the algebraic diagrammatic construction to the second-order [ADC(2)] using the SV(P) basis sets. The ground state was described with the Møller-Plesset perturbation theory to the second-order (MP2) with the same basis set. The S1 and S2 states were optimized at the ADC(2)/SV(P) level. Up to 10 excited states were computed. No symmetry restrictions were imposed.
