O2 and N2 do have very weak absorption / emission lines in the LWIR range.
The second effect comes from the fact that CO2 colliding with itself in a tube of pure CO2 broadens the lines about 30 % more than does CO2 colliding with N2 or O2 in air, which results in an additional slight overestimate of the absorption in the laboratory experiment.
OK so please describe in detail the mechanism by which N2 and O2 radiate this energy if it is not by the movement of electrons between different energy states (as a consequence of the vibrational modes of the molecule) which causes the characteristic absorption and emission lines.
«Abstract - Over 5000 absolute absorption values for pressure - broadened O2 lines in dry air were measured at frequencies from 49 to 67 GHz in O.l - GHz - increments.
