[en] Spectral lines from intermediate stages of ionization in Mo were measured and identified. The Mo spectra were observed from a laser-produced plasma and vacuum-spark data. The wavelengths of the 3d¹⁰-3d⁹4p, 4f transitions in Mo XV and the 3p⁶3d⁹-3p⁵3d¹⁰ lines in Mo XVI were measured with an estimated accuracy of +- 0.010A. Line classifications were obtained in complex spectral arrays in Mo XIV-XVIII. These were made with the aid of relativistically-corrected Hartree-Fock calculations. Energy-level diagrams were constructed for the 3d⁸4p and 3d⁸4f configuration in Mo XVI
