How to find the absorption spectrum of $O_2$O2 and $N_2$N2?

I am new to spectroscopy, so I am not sure how my questions are perceived. I just want to make sure that I am not lost, so any kind of suggestion is welcome.

I am interested in the infrared absorption spectrum of molecular nitrogen and oxygen. I thought it would be more streamlined to obtain this information, but it is not easy as I thought.

What I did is, I went to the HITRAN database and downloaded the linestrengthsline strengths of both $N_2$$\ce{N2}$ and $O_2$$\ce{O2}$, and I extracted the $\texttt{.par}$ file, and I am able to see some obvious peaks.

I also have a range of interest for both temperature (~70-300 K) and pressure (~300-3000 Pa), but I don't know where to start.

Another point of confusion for me is as follows: On the NIST page for $CO_2$$\ce{CO2}$, the is a section titled "IR spectrum", which clearly shows absorption/emissions spectrum of $CO_2$$\ce{CO2}$. However, such a section does not exist for nitrogen or oxygen. Why is there no section for this?

How do I go about finding absorption spectrum for $N_2$$\ce{N2}$ and $O_2$$\ce{O2}$ in my range of interest? Should I simply google keywords and try to see if I can find what I find on Google image search?
