Abstract: Spin-orbit Configuration Interaction calculations based on Relativistic Effective Core Potentials (RECPs) were used for the study of the linear $NpO^{2-}_{2}$ and $NpO^{+}_{2}$ ions. The ground state of $NpO^{2+}_{2}$ is $\frac{5}{2}u(^{2}\Delta_{u} + {^{2}}\Phi_{u})$ with equilibrium Np-O bond distance, $R = 1.66 {\AA}$ and symmetric stretch vibrational frequency, $\omega=1059 cm^{-1}. NpO^{+}_{2}$ has a $4_{9} (^{3}H_{4g}, \delta_{u}\phi_{u})$ ground state with $R=1.73 {\AA}$ and $\omega=913 cm^{-1}$. The spectra for both ions have $f\to f$ transitions at low energies and charge-transfer type transitions at higher energies.
