Later that year, English astronomer Joseph Lockyer observed the same spectral line, wrote a paper and also sent it to the French Academy of Sciences.

If the atoms are excited, they emit these same wavelengths, hence one can determine precisely which spectral lines belong to which element.
At the same time, the new model itself is so general that it will offer an interesting starting point for the search for dark matter even if it turns out that the spectral line discovered in 2014 has a different origin.
Empirical evidence using spectroscopy proves that a gas does not absorb spontaneous emission from a body which is significantly cooler than it, but it does absorb (and spectral lines thus appear) when the same body is made warmer than the gas.
On the other hand, once water is present, its IR spectral lines overlap with those of CO2 and make CO2 less potent a greenhouse gas — for the same reason why the temperature dependence on CO2 concentration becomes logarithmic: the previous molecules have already done much of the effect, anyway.
I also understand to about the same extent, how those spectral lines can have a «fine structure» producing several lines instead of one; due to refinements first proposed by Arnold Sommerfeld and others.
