This free version of Molcas is primarily used to perform excited state electronic structure computations with multiconfigurational CASSCF/RASSCF and CASPT2/RASPT2 methods, but it also features a number of DFT functionals and other correlation methods, continuum solvation approaches, geometry optimizations optimization and molecular dynamics. It contains a large part of the original Molcas codebase that has been released as free and open-source software. Further documentation can be found at https://molcas.gitlab.io/OpenMolcas/sphinx/
