Résumé : Forty cold bands and 29 hot bands are reported from the high resolution Fourier transform (FT) absorption spectrum of 13CH12CH, all leading to vibrational states located between 6750 and 9500 cm-1. Each of these bands has been vibrationally assigned and rotationally analysed. The band centres (νc), vibrational term values (Gv) and rotational constants are listed.
