What Does FOA Stand For?

FOA stands for Frozen Orbital Approximation

The Frozen Orbital Approximation (FOA) is a computational technique used in quantum chemistry and molecular modeling. It simplifies the treatment of electronic structure by fixing the orbitals of certain electrons, allowing for a more manageable calculation of interactions among remaining active electrons. This method is particularly useful in studies of excited states and in cases where computational efficiency is critical, as it reduces the complexity of wavefunction calculations while still providing valuable insights into molecular behavior.
