All electron CAS+MRCI calculations are performed for the X $^2 \\Sigma_{u}^+$ and B $^2 \\Sigma_{g}^+$ states, while valence CAS+MRCI calculations using an effective core potential are used to describe the A $^2\\Pi_u$ state. A double well is found in the B $^2 \\Sigma_{g}^+$ state. Spectroscopic constants, vibrational levels, transition moments and radiative lifetimes are calculated for the most abundant isotope of calcium ($^{40}$Ca).
