What Does CPHF Stand For?

CPHF stands for Coupled Perturbed Hartree Fock

CPHF, or Coupled Perturbed Hartree Fock, is a quantum chemistry method used to compute the response of electronic systems to external perturbations. It extends the Hartree Fock approach by incorporating coupling between electronic states, enabling accurate predictions of properties such as molecular vibrations, electronic spectra, and reaction dynamics. CPHF is particularly valuable in calculations involving correlated electron systems and offers a robust framework for assessing the effects of perturbations on molecular stability and behavior.
