Pair Correlation Theories,ell-known characterization of an atomic state by its configuration,. e.g., for the carbon ground state 1s.2s.2p., without specifying the m. and m. values. (For a general discussion of closed- and open-shell states in the framework of rigorous quantum mechanics, see Refs. 2 and 3.)

The Multiconfiguration Self-Consistent Field Method,“suffiiciently” accurate for most of the interesting properties of a chemical system. Second, the successful implementation of the single configuration SCF method was diffiicult and the implementation of the more complex MCSCF framework proved to be significantly more arduous.

One could also attempt to solve the time-dependent Schrödinger equation directly, e.g., in the time-dependent Hartree—Fock approximation. The approach to these dynamical properties of atoms and molecules which we will discuss is based on the equat
