What Does BSSEC Stand For?

BSSEC stands for Basis Set Superposition Error Correction

BSSEC, or Basis Set Superposition Error Correction, refers to a computational chemistry method used to address the inaccuracies that arise in quantum mechanical calculations due to the incomplete basis sets utilized in modeling molecular systems. This technique systematically corrects for the basis set superposition error (BSSE), which can lead to erroneous energy and molecular property calculations by accounting for the effects of basis set overlap between interacting molecular entities. By implementing BSSEC, researchers can enhance the reliability and accuracy of their computational predictions in the study of molecular interactions and reactions.
