The second electric dipole hyperpolarizability of the lithium atom is calculated using a series of multiconfiguration SCF wave functions with an increasing number of active space orbitals. In agreement with other recent calculations, we find a very large correlation correction to the hyperpolarizabi

β¦ Synopsis
Multicontiition self-consistent tield+configuration interaction wavefunctions were used to compute potential energy curves of the lowest doublet and quadruplet states of CO*. Spin-orbit splitting the three lowest 'II states and dipole moment for the X *Z+, A 'IL and D 'lT states bave been determined. Transition moments for the A 'D-X 'Z+, D 'II-X 'Z+, ( 3)*lI-X 'Ef, D *II-A 'IT and B *2+-A *II transitions have been calculated. Theoretical oscillator strengths for the D 'D-X 2X+ and D ZlT-A21T transitions were calculated and the results show that these transitions could be observed.

The electronic and vibrational properties of CNadsorbed on Pt electrodes have been studied through MCSCF calculations on the molecular ions PtCN-and PtNC-. The results are in good agreement with experimental results obtained in situ by the non-linear optical technique of sum frequency generation.
