Software developed and maintained by the Duesseldorf Theoretical Chemistry group:
The DFT/MRCI program combines Kohn-Sham density functional theory and multi-reference configuration interaction for reliable and fast calculation of electronically excited states.
The COBRAMM package interfaces widely known commercial and academic softwares for molecular modeling. It allows simulations in ground and excited states, bridging from the atomistic (QM) to the nanoscale (QM/MM).
