Welcome to the documentation for the ORCA SEAMM plug-in#

This plug-in runs the ORCA quantum-chemistry program from a SEAMM flowchart: single-point energies and geometry optimizations at Hartree–Fock, MP2, coupled-cluster (DLPNO-CCSD(T)), and DFT (the full range of ORCA functionals, including double hybrids), with energies, forces, and a wide set of properties.
