Studies in the optical spectrum of singly ionized sodium, Na II

University of British Columbia

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).
