What Does CIPSO Stand For?

CIPSO stands for Configuration Interaction With Perturbation Including Spin Orbit Coupling

CIPSO, or Configuration Interaction With Perturbation Including Spin Orbit Coupling, is an advanced computational method used in quantum chemistry and molecular physics. It combines configuration interaction techniques with perturbative corrections to account for spin-orbit coupling effects. This approach enhances the accuracy of electronic structure calculations, particularly for systems where relativistic interactions play a significant role, enabling more precise predictions of molecular properties and behaviors in various chemical environments.
