Energy levels, fine-structure separations, specific mass shift parameters, isotope shifts, hyperfine interaction constants, Lande g(J)-factors and transition probabilities are reported for the 2s(2)2p(2)-2s2p(3) transition array in N II, O III, F IV, Ne V and Ti XVII. Wavefunctions were determined using the multiconfiguration Dirac-Hartree-Fock method with account for valence, core-valence and core-core correlation effects. The transition energies and rates are compared with experimental data and with values from other calculations.
