High-resolution FTIR analysis and rotational constants for the ν12 band of ethylene-1-13C (13C12CH4)

First theoretical global line lists of ethylene (12C2H4) spectra for the temperature range 50−700 K in the far-infrared for quantification of absorption and emission in planetary atmospheres

“…A preliminary analysis of line positions the 1.6 µm region was carried out using a very crude effective model, including only the ν 5 + ν 9 /ν 5 + ν 11 system (Lorono et al 2010). A series of papers was devoted to the study of ethylene isotopologs (see De Vleeschouwer et al 1982;Flaud et al 2011Flaud et al , 2010Tan et al 2015b,a;Ulenikov et al 2015;Gabona et al 2014;Gabona & Tan 2014a,b;Tan & Gabona 2012, and references therein). Most available analyses of ethylene laboratory spectra only consider line positions.…”
