The fundamental bending ro-vibrational bands and a number of overtone, combination and hot bands of 13C2HD have been recorded by Fourier transform infrared spectroscopy (FTIR) in the range 450-2100 cm-1. In addition, the v5-v4 band, centred at 164.65 cm-1, has been identified in a spectrum of 13C2H2. The data have been analysed simultaneously in a global fit that has provided very accurate rotational and vibrational parameters for the ground and for the vibrationally excited states.
