The sulfurlike spectra of copper through molybdenum have been identified from observations in tokamak- and laser-generated plasmas. Wavelengths of electric-dipole transitions of the 3s23p4–(3s3p5 + 3s23p33d) array in the range 75 to 305 Å are given. The wavelength uncertainty is estimated to be ±0.007 Å. These data have been combined with previously reported wavelengths of magnetic-dipole transitions to determine energy levels for the isoelectronic sequence Cu xiv through Mo xxvii including Rb and Sr for which no observations were made. Ground configuration intervals obtained from magnetic-dipole transitions are compared with Dirac–Fock calculations to predict unknown values and to correct misidentifications. Wavelengths previously classified as chlorinelike
in Cu through Zr are now classified as sulfurlike lines. A new set of observed and interpolated wavelengths for that transition is presented for Cu through Kr.

Wavelengths between 2000 Å and 5 μm are values in air. Newly predicted values are preceded by the symbol *. The remainder are observed values from Ref. 1. Uncertainties are included in parentheses.
Values in Ref. 1 of 1268.7(2) and 868.4(2) Å are replaced by the new predicted wavelengths.
Values in Ref. 1 of 1572.9(10) and 833.1(2) Å are replaced by the new predicted wavelengths.

Wavelengths are in angstroms; those given in parentheses are predicted values derived from the HFR calculations and the O − C curves. Intensities are visually estimated from the plate blackening. The symbol bl indicates a blend of unresolved or close lines; m indicates that the line is masked by an impurity line.
This line is also classified as Cu xviii.
