The potential energy curves and transition moments of the ground state of Ca2and1Σ+ustates correlating with the1S +1P and1S +1D calcium atoms have been calculated. The calculations support the assignment of the observed emission spectra of Ca2in the red and in the green to transitions between the ground state and the 1,21Σ+ustates. Predissociation of the 11Σ+ustate is also shown to be possible from an interaction with the 13Πustate. © 1982.
