CO${}_2$ collision-induced line parameters for the $\hat{I}{½}_3$ band of ${}^{12}$CH${}_4$ measured using a hard-collision speed-dependent line shape and the relaxation matrix formalism

Thibault Bertin, Jean Vander Auwera

Ten high resolution Fourier transform spectra of the pentad region near 3.3 μm of methane diluted in carbon dioxide at total pressures up to 800 hPa have been recorded at 296.5(5)…
