The torsion-rotation spectrum of $D2O2$ has been recorded in the region from 25 to $600cm-1$ at a resolution (1/MOPD) of $0.003cm-1$ 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 value up to 30 and 11 respectively. The current state of the analysis will be described.
