Phosphoruslike spectra Cu XV to Mo XXVIII have been identified in tokamak- and laser-produced plasmas in the wavelength range of 83 to 163 A. These were obtained with the text tokamak at the University of Texas and the 1-GW Nd:glass laser at the National Institute of Standards and Technology, using 2.2- and 10.7-m grazing-incidence spectrographs, respectively. Wavelength measurements were made with an uncertainty of {plus minus}0.005 A. All the classified lines arise from the 3{ital s}{sup 2}3{ital p}{sup 3}--3{ital s}{sup 2}3{ital p}{sup 2}3{ital d} array. They were identified through detailed comparisons with Hartree--Fock calculations of wavelengths and relative intensities along the isoelectronic sequence. All spectra from Cu to Mo were observed, except for Rb and Sr, whose wavelengths are predicted by interpolation with an uncertainty of {plus minus}0.02 A. By means of previously observed magnetic-dipole (M1) lines within the 3{ital s}{sup 2}3{ital p}{sup 3} ground configuration and comparisons with published Dirac--Fock calculations, all the energy levels of this configuration were determined with an uncertainty of {plus minus}10 to 100 cm{sup {minus}1} for Co to Mo. These levels were used to predict all the M1 wavelengths. A correction to the Co XIV ground configuration is made by means of a previously published list of M1 lines.
