The Dalton program system can also be used to perform Second-Order Polarization Propagator Approximation (SOPPA) calculations [49,51,62,63] or Second-Order Polarization Propgator Approximation with Coupled Cluster Singles and Doubles Amplitudes [SOPPA(CCSD)] calculations of optical properties like singlet or triplet excitation energies and oscillator strenghts as well as the following list of electric and magnetic properties
