The Matrix

The purpose of the present paper is to give further details of an investigation of the spin–orbit interaction in diatomic molecules. The first part of the paper deals with perturbations between states of odd multiplicity in a two-electron system. With the aid of the matrix elements which have been obtained, a comparison of the perturbations in the various components of a given state and in some cases a comparison of perturbations in two different states is possible. Also for certain cases it has been possible to establish relationships between the matrix elements which give the magnitude of the perturbations and experimentally measurable molecular constants of the perturbed states.

Mass Dependent

The nuclear-mass dependent spin-orbit interaction is discussed. The corresponding interaction operator is given in tensor form and the expression for its matrix elements in a basis of SL functions is presented. Monoconfigurational calculations have been performed for the ground states of carbon and oxygen. The results for the J-level splittings show that the contribution from this interaction is comparable with, or even greater than, the contribution from the hyperfine-structure interactions.
