## Abstract The time‐dependent variational principle is used to calculate the frequency‐dependent dipole polarizabilities of 2__p__ open‐shell atomic systems. A general theory is built up to include frequency‐dependent perturbations using the Roothaan–Hartree–Fock (HFR) formalism. The excitation en

## Abstract Two previous schemes for the calculation of dynamic multipole polarizabilities of atomic systems, namely, a hydrodynamic analogy to quantum mechanics and a perturbation expansion of the energy in multipoles, follow also from the conventional time‐dependent perturbation scheme.
An analytical approach employing the closed form of the Green function for the generalized Coulomb problem is presented for the description of the optical properties of the Li atom. Rydberg states of atoms and molecules have attracted much attention for a long time. The weakness of the interaction
## Abstract Static dipole polarizabilities and shielding factors for the 2__p__ open shell atomic systems are presented using coupled Hartree Fock theory in the framework of the Roothaan formalism. Calculations have been performed for the ground as well as for some valence excited states. A variati
