The IR spectrum of 12C2H2: line intensity measurements in the 1.4 µm region and update of the databases
Résumé
Spectroscopic data are noticeably enriched in six spectral regions of the main isotopologue 12C2H2 of the acetylene molecule, namely, in the regions around 3, 2.2, 1.9, 1.7, 1.5, and 1.4 µm. Among these regions, only those at 3 and 1.5 µm were already presented partly in the databases. The results of line intensity measurements, performed for the first time in the 1.4 µm region, are given. Data available in the literature, or obtained in the present work, are compiled to set up line lists usable for applications in the quoted spectral regions. On the whole, 5748 new lines pertaining to 65 bands can be added to the databases.
