The arc and spark spectra of antimony have been photographed in the region from λ 400 Å to λ 9000 Å.
Out of the approximately 5000 lines measured, one thousand five hundred and fifty eight lines have been classified as transitions between three hundred and seventy eight established levels in the spectra of SbI, SbII, SbIII, SbIV and SbV. The transformation theory of atomic spectra has been applied in detail to all the simple configuration encountered in the analyses. The Slater parameters and Landé interval factors have been calculated from the observed values of the energy levels of the configurations. The standard deviation between calculated and observed energy levels is generally about two or three percent of the configuration width. The theory of inter-configuration perturbation has been applied successfully to analyse the levels of the SbIV configuration,where 5p² and 5s5d mutually perturb and also the levels of SbIII where a perturbation occurs between 5s5p² and 5s²5d. It was generally observed that the Landé interval factors increase as the energies of parent configurations increase, while the Slater parameters remain rather constant. This relative change implies that the coupling scheme tends to the (jj) extreme in more highly excited ions and in members with higher principal quantum numbers in a Rydberg series. It is also observed that as the nuclear change increases, the coupling scheme tends to be more jj. / Science, Faculty of / Physics and Astronomy, Department of / Graduate
