Spectroscopic parameters of the ground state X<sup>1</sup>Σ<sup>+</sup> have been evaluated and critically compared with the available experimental values and the other theoretical data. However, spectroscopic parameters of 1<sup>3</sup>Π, 1<sup>1</sup>Δ, 1<sup>1</sup>Σ<sup>−</sup>, 1<sup>1</sup>Π, 1<sup>3</sup>Σ<sup>+</sup>, 2<sup>3</sup>Σ<sup>+</sup>, 1<sup>3</sup>Δ, 1<sup>3</sup>Σ<sup>−</sup>, 2<sup>3</sup>Π, 2<sup>1</sup>Π, 3<sup>3</sup>Π, 3<sup>1</sup>Π and 3<sup>3</sup>Σ<sup>+</sup> states are studied for the first time. These 13 excited states have shallow potential wells, and the dispersion coefficients of these excited states are predicted. In additional, oscillator strengths of excited states at equilibrium distances are also predicted.</p></div>
