What Does FSMRCC Stand For?

FSMRCC stands for Fock Space Multireference Coupled Cluster

FSMRCC, or Fock Space Multireference Coupled Cluster, is a sophisticated computational method used in quantum chemistry to accurately describe electronic correlations in systems with multiple electronic states. By employing the Fock space formalism, FSMRCC facilitates the treatment of systems where conventional single-reference approaches may fail, particularly in cases of strong correlation and near-degenerate configurations. This method leverages coupled cluster theory to provide a balanced and effective means of modeling complex electronic interactions, making it a valuable tool for researchers studying molecular systems and reactions.
