In auroras and airglows, there are evidences that the b1Σg+→X3Σg− forbidden transition of O2 at 762 nm can contribute the emission light, but this emission can be absorbed then by the oxygen in the atmosphere. Therefore, the reddish 762 nm emission of O2 may only be observed from space. On the other hand, we can observe the reddish emission of the excited N2 molecule on the surface of the Earth. Why is the emission of N2 not absorbed by the nitrogen in the atmosphere?
