Prediction of new spin-forbidden transitions in the N molecule-the electric dipole A'Σ → AΣ and magnetic dipole a'Σ ← AΣ transitions.

On the ground of multi-reference configuration interaction calculations with an account of spin-orbit coupling, we have predicted the probability of two unknown spin-forbidden transitions in the spectrum of the N molecule: the electric dipole A'Σ → AΣ emission system and the magnetic dipole a'Σ ← AΣ transition. The radiative lifetime of the lowest A'Σ sublevel is less than a microsecond; the magnetic transition induced by the spin current in the triplet state is predicted with relatively low oscillator strength (f = 10), which still could be detectable.
