The newly developed high resolution Fourier-transform intra-cavity laser absorption spectroscopy (FT-ICLAS) was utilized to record the νOD=5 stretching overtone of HOD at a resolution of 0.05 cm-1 in the region 12550–12900 cm-1. The spectrum was rotationally analysed and the spectroscopic parameters were derived from nonlinear least-squares fitting. Good agreement of the observed with the calculated energy levels was achieved.
