Abstract

The infrared spectrum of a sample containing C-13 mono-substituted isotopologues of acetylene, (HCCH)-C-12-C-13, (HCCD)-C-12-C-13, (DCCH)-C-12-C-13 and (DCCD)-C-12-C-13 has been recorded in the 6130-6800cm(- 1) region using a femto-Fourier transform-cavity enhanced absorption spectroscopy (femto-FT-CEAS) apparatus. Three bands for both (HCCD)-C-12-C-13 and (DCCH)-C-12-C-13 were observed and analysed, namely 2(1) - GS and associated hot bands from (4) and (5). The assignment of the 2(1) 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 (DCCD)-C-12-C-13 isotopologue, four bands were analysed, (1) + (2) + (3) - GS and associated hot bands from (4) and (5) and 2(1) + (4) + (5) - GS
