In this paper benchmark results are presented on the calculation of vertical electronic excitation energies using a long-range second-order polarisation propagator approximation (SOPPA) description with a short-range density functional theory (srDFT) description based on the Perdew-Burke-Ernzerhof (PBE) functional. The excitation energies are investigated for 132 singlet states and 71 triplet states across 28 medium sized organic molecules. The results show that overall SOPPA-srPBE always performs better than PBE, and that SOPPA-srPBE performs better than SOPPA for singlet states, but slightly worse than SOPPA for triplet states when CC3 results are the reference values.
