The torsion-rotation spectrum of D₂O₂ has been recorded in the region from 25 to 600 cm^-1 at a resolution (1/MOPD) of 0.003~cm^-1 using a modified Bomem Fourier transform spectrometer. The aim of the study is to improve the torsional potential of D₂O₂ and to locate the weak oxygen-oxygen stretching fundamental which should lie amongst the torsional levels. So far, the pairs of torsional levels with n=0, 1 and 2 and one of the levels with n=3 have been analysed with J and K values up to 30 and 11 respectively. The current state of the analysis will be described.
