Use of 2h and 3h-p-like coupled-cluster Tamm-Dancoff approaches for the equilibrium properties of ozone

Equation-of-motion coupled-cluster theory in a 2h and 3h - p-like TDA approach has been utilized to determine properties of the ground state of ozone (O-3). many of the values produced with this scheme are better than those obtained with other approaches with similar computational scaling properties.
