The Rotational-Translational Spectra of N2 and CO2 and their Mixtures with Argon: Experimental Investigation

As a result of molecular pair collisions, the rotational-translational absorption spectra of carbon dioxide, nitrogen, and their mixes with argon in the wavelength range 20-190 cm-1 are acquired and analysed. The terahertz spectra of N2 and CO2 are shown to be dominated by quadrupole interactions, as opposed to absorption in noble gas combinations. The integrated…
