The spectrum of Mo XIV was observed with a low-inductance spark and a laser-produced plasma in the region from 70 to 630 Å on the 10.7-m grazing-incidence spectrograph at NBS. From the identification of 35 lines, a system of 22 energy levels was determined. The level system (Cu ι isoelectronic sequence, 3d10nl) includes the series ns (n = 4–6), np (n = 4–6), nd (n = 4,5), nf (n = 4–6), and ng (n = 5–7). The observed energy levels are compared with Hartree-Fock calculations. The ionization energy is determined from the ng series (n = 5–7) to be 2 440 600 ± 300 cm-3 (302.60 ± 0.04 eV).
