High resolution spectrum of the trans-C2H2D2 molecule is analyzed on the basis of the Ground State Combination Difference method in the region 1450–1650 cm–1, in which the hybrid ν7 + ν8 band is located. The analysis is performed in the framework of the model which takes into account the Coriolis interaction with the ν8 + ν10 band. The b-type transitions that in their turn, allow more experimental data on the ν7 + ν8 band to be obtained, are determined for this band for the first time.
