Experimental data for the rotational spectrum of carbon monoxide (CO) at two temperatures is available here:
CO-rot-300.txt
(300 K)CO-rot-1500.txt
(1500 K)The low-pressure, high resolution spectrum of phosphine, \( \mathrm{PH_3} \), in the region \( 0 -- 200\;\mathrm{cm^{-1}} \) is provided in the text file PH3-spec.txt
. The line list for phosphine in this region is PH3-lines.txt
.
A Jupyter Notebook with an interactive plot of the rotational energy level populations of a diatomic molecule is available: interactive-rotational-populations.zip. You can also run this Notebook in MyBinder here.
