Spin-adapted Configuration Interaction

Spin-Adapted Configuration Interaction is a configuration interaction method that employs spin eigenfunctions as basis states to ensure the wavefunction is an exact eigenstate of the total spin operator, thereby preserving spin symmetry throughout the variational calculation.
