Method of configuration interaction in calculations of the spectral characteristics of atoms and molecules

For He, Be, Ne, and Mg atoms and their isoelectronic series, calculations of the dipole dynamic polarizability, energies, and strengths of the oscillators of the lowest electronic transitions are made within the scope of the method of configuration interaction. This very method is also used to calculate the dipole dynamic polarizability of a number of molecules of hydrides and N₂ and CO₂ molecules.
