The 3p/sup 6/ 3d/sup 8/--3p/sup 5/ 3d/sup 9/ transitions in Sr XIII, Y XIV, Zr XV, Nb XVI, and Mo XVII have been newly measured by means of a low-inductance vacuum spark and a 10.7-m grazing-incidence spectrograph. The measurements have led to an improved analysis of this complex transition group in these ions. All levels of the combining configurations have been established. The energy parameters determined from least-squares fits to the observed levels are compared with Hartree--Fock calculations. The effective interaction aL(L+1) for the 3p/sup 6/3d/sup 8/ configuration decreases markedly with increasing ionization. The effective electrostatic interactions D/sup 1/(3p3d) and X/sup 2/(3p3d) for the 3p/sup 5/3d/sup 9/ configuration are practically constant through the sequence.
