The weak ν3 + ν10(Bu) hybrid band of the trans-C2H2D2 molecule in the region of 1910–2000 cm–1 has been assigned for the first time. The spectrum is analyzed based on the method of ground state combination differences. More than 300 energy levels (Jmax = 20, Ka max = 9) have been determined using the experimental data. Rotational parameters of the ν3+ν10(Bu) band are obtained.
