Аннотация:A comprehensive deperturbation analysis is made of the singlet-triplet D(1)Pi similar to d(3)Pi complex of the (23)Na(39)K molecule. The deperturbation model takes into account direct spin-orbit coupling between the singlet and triplet states plus a spin-rotational interaction between different Omega components of the triplet state. The direct inversion procedure provides a self-consistent set of the Dunham molecular constants for both states and for the matrix elements of the spin-orbit interaction. The deperturbation analysis is supported by electronic structure calculations performed in the framework of the relativistic effective potential method combined with many-body multipartitioning perturbation theory. The theoretical spin-orbit matrix elements agree well with their experimental counterparts.
