The potential energy curves of X ²Σ⁺, A ²Π, B ²Σ⁺, a ⁴Σ⁺, and b ⁴Δ states and their Ω states of CP were calculated using the icMRCI approach. The transition dipole moments between these states were computed. To improve the accuracy of the potential energy curves, core–valence correlation and scalar relativistic corrections were considered. The radiative lifetimes were approximately 10 μs for the A ²Π_3/2 and A ²Π_1/2 states and 100 ns for the B²Σ⁺_1/2 state; those were approximately 10, 10 – 100, 10, 0.1 – 1, and 10 ms for the a ⁴Σ⁺_1/2, a ⁴Σ⁺_3/2, b ⁴Δ_1/2, b ⁴Δ_3/2, and b ⁴Δ_5/2 states, respectively. The spontaneous emissions from the B ²Σ⁺_1/2 – X ²Σ⁺_1/2 system were strong, followed by the A ²Π_3/2 – X ²Σ⁺_1/2, A ²Π_1/2 – X ²Σ⁺_1/2, B ²Σ⁺_1/2 – A ²Π_3/2, and B ²Σ⁺_1/2 – A ²Π_1/2 transitions. The strong emissions from the A ²Π_3/2 – X ²Σ⁺_1/2 and A ²Π_1/2 – X ²Σ⁺_1/2 systems were in the infrared region; those from the B ²Σ⁺_1/2 – X ²Σ⁺_1/2 system were in the visible and ultraviolet regions; and those from the B ²Σ⁺_1/2 – A ²Π_3/2, and B ²Σ⁺_1/2 – A ²Π_1/2 systems were of visible light. A simple comparison shows that the effect of the spin–orbit coupling on the radiative lifetimes of the A ²Π and B ²Σ⁺ states was significant. The radiative–lifetime distribution of each level υ versus the rotational quantum number J was evaluated for υ ≤ 15 and J ≤ 70.5.
