What Does HFFC Stand For?

HFFC stands for Hartree Fock Frozen Core

HFFC, or Hartree Fock Frozen Core, is a computational chemistry method that simplifies the calculation of electronic structure in atoms and molecules. It involves freezing certain core electrons in their ground state to reduce computational cost while allowing the remaining valence electrons to be fully optimized. This approach enhances efficiency in quantum mechanical calculations, making it particularly useful in large-scale molecular systems where precision and resource management are critical. HFFC is commonly employed in quantum chemistry software for predicting molecular properties and behaviors.
