The accuracy of the SAC-Cl (symmetry-adapted-cluster configuration-interaction) method is examined for the singlet and triplet excited states of Hz0 by comparison with the full-Cl results for the [4s2p] basis set. The SAC-C1 results for the excitation energy agree with the full-Cl results to within
