Spectra of Yb IV produced with a low voltage sliding spark discharge were photographed in the range of 700 to 2200 A with a 10.7 m normal incidence spectrograph. Wavelengths for 944 spectral lines identified as Yb IV were measured. Of these, 535 were classified as transitions between 95 even and 51 odd energy levels of the 4f/sup 13/, 4f/sup 12/5d, 4f/sup 12/6s, and 4f/sup 12/6p configurations. Values for the interaction parameters were derived by a least squares fit to the known levels.
