Complete active space

In quantum chemistry, a complete active space (CAS) is a systematic classification of molecular orbitals used to construct multireference wavefunctions. Orbitals are partitioned into three classes—core, active, and virtual—and a configuration interaction expansion is carried out over all possible distributions of a chosen number of electrons among the…
