| Abstract: | Ab initio calculations in the “first-order wavefunction” CI approximation have been performed for several states of N2+ with 2Σu+, 2Σu?, 4Πu symmetry. A calculation of the electronic factor of the vibronic interaction between the B2Σu+ and C2Σu+ states seems to support the suggestion of Tellinghuisen and Albritton that the C state is predissociated by the continuum of the B state through nuclear momentum coupling. |
