Radiative lifetimes of 13 odd-parity levels of Mo II have been measured using time-resolved laser-induced fluorescence (TR-LIF) spectroscopy in a plasma produced by laser ablation. The investigated levels, within the energy range 48 022 − 63 497 cm-1, were excited from the ground or appropriate metastable states with one-photon selective excitation. The uncertainties of the measured lifetime results are less than 10%. Calculated lifetimes of Mo II, obtained using the relativistic Hartree-Fock (HFR) method including core-polarization effects, are found to agree well with the measured ones. New transition probabilities are deduced for 246 transitions in the wavelength range extending from 207.431 up to 510.813 nm.
