Extrapolating to the One-Electron Basis Set Limit in Polarizability Calculations

We report calculations of polarizabilities using total energies extrapolated to the complete basis set limit. A dual-level scheme has been employed, with the complete basis set limit of the correlation energy determined by the recently reported uniform singlet- and triplet-pair extrapolation method. The finite field approach has been employed, with tensors and averaged polarizabilities for the ground electronic states of H2, N2, CO, and H2O reported and compared with available experimental data in the literature. Exploratory results are also presented for C6H4NO2NH2
