The fundamental ro-vibrational bands and the 2ν₄←GS, 2ν₅←GS, 2ν₃←GS, ν₄+ν₅←GS, ν₃+ν₄←GS, ν₃+ν₄←ν₄, ν₃+ν₅←ν₅, overtone, combination and hot bands of the two rare isotopologues of acetylene H12C13CD and H13C12CD have been detected by Fourier transform infrared spectroscopy (FTIR). The analysis of the data has provided very accurate rotational and vibrational parameters for the ground and for the vibrationally excited states.
