Applications of the Dirac Slater model to obtain relativistic energy levels and wave functions for molecules are reported. Results are presented for the uranyl ion UO 2+ 2 , calculated by a discrete‐variational method using numerical free‐atom basis functions. A simple moment polarized generalization of the Slater exchange potential is proposed for treating open‐shell systems; results for a 5 d atom are compared with corresponding nonrelativistic spin‐polarized states.
