The spectrum of the singly ionized sodium ion, Na II, has been photographed in the region between 350 Ɣ and 9000 Ɣ using as sources a condensed electrodeless discharge and a condensed spark in helium. Exposures were taken on a 3-meter normal-incidence vacuum grating spectrograph,
on a 21-foot concave grating spectrograph, on a Hilger E-478 large interchangeable quartz and glass prism spectrograph, and Fabry-Perot interferometer. The term system has been revised and much extended. Five hundred and twenty-seven lines (with twenty doubly identified) are
classified as combinations between sixty-two odd levels and seventy-one
even levels. The ionization limits, 2s² 2p⁵(²P₃⁄₂) and 2s² 2p⁵ (²P₁⁄₂),
have been redetermined as 381390.2 cm⁻¹ and 382756.6 cm⁻¹ (±2.0 cm⁻¹). / Science, Faculty of / Physics and Astronomy, Department of / Graduate
