This comes from the fact that carbon dioxide, a gas which is invisible, odourless and tasteless, allows radiated energy to pass on through it while the much more common nitrogen and oxygen do not.Erm… I think that this is the wrong way round – CO2 does NOT allow radiated energy to pass through, while N2 and O2 DO.

I think you are right when talking about the infrared. Any molecule (with more than one atom :) ) can absorb and re-emit another photon, but not necessarily in the infrared.

IR does pass through. There is a reaction after which other events can occur. In certain circumstances, the raised energy state can endure for a period and energy is then absorbed. At radiative equilibrium, all photons are, essentially, just passing through. N or O do not react in this way.
From my reference (ii) which illustrates the point about about time.
