Abstract

The theoretical study of Rydberg states fine structure is of great importance for several problems in the atomic and molecular spectroscopy. Although rather well developed for the Rydberg states in atoms and dipoleless molecules, the fine structure theory has not been constructed for the Rydberg state in dipole molecules. In this case, the broken spheric symmetry necessarily complicates the theory. The relativistic corrections contain now not only spin-orbital interaction, as it take place in atoms, but also some additional terms that can be interpreted as "spindipole" interaction. The correspondent addition to the Rydberg electron Hamiltonian is proportional to r⁻³.
