Abstract

New observations of the spectrum of Pt ii have been made with hollow-cathode lamps. The region from 1032 to 4101 Å was observed photographically with a 10.7-m normal-incidence spectrograph. The region from 2245 to 5223 Å was observed with a Fourier-transform spectrometer. Wavelength measurements were made for 558 lines. The uncertainties vary from 0.0005 to 0.004 Å. From these measurements and three parity-forbidden transitions in the infrared, accurate values were determined for 28 even and 72 odd energy levels of Pt ii.
