Résumé :

The infrared spectrum of a sample containing 13C mono-substituted isotopologues of acetylene, H12C13CH, H12C13CD, D12C13CH and D 12C13 CD has been recorded in the 6130-6800 cm -1 region using a femto-Fourier transform-cavity enhanced absorption spectroscopy (femto-FT-CEAS) apparatus. Three bands for both H 12C13CD and D12C13CH were observed and analysed, namely 2ν1 - GS and associated hot bands from ν4 and ν5 . The assignment of the 2ν1 overtone already reported in the literature [J.L. Hardwick, Z.T. Martin, M.J. Pilkenton, E.N. Wolf, J. Mol. Spectrosc. 243, 10 (2007)] was considerably extended to higher J values. For the D12C13CD isotopologue, four bands were analysed, ν1 + ν2 + ν3 - GS and associated hot bands from ν4 and ν5 and 2ν1 + ν4 + ν5 - GS. © 2013 Taylor & Francis.
