Prediction of new spin-forbidden transitions in the N 2 molecule-the electric dipole A' 5 Σ g + → A 3 Σ u + and magnetic dipole a' 1 Σ u - ← A 3 Σ u + 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 2  molecule: the electric dipole A' 5 Σ g + → A 3 Σ u + emission system and the magnetic dipole a' 1 Σ u - ← A 3 Σ u + transition. The radiative lifetime of the lowest A' 5 Σ g + 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 -10 ), which still could be detectable.
