✦ Synopsis

The infrared absorption spectrum of the (v_{2}) band of deuterated nitric acid (\left(\mathrm{DNO}{3}\right)) has been measured on a Bomem DA3.002 Fourier transform spectrometer in the wavenumber region (1640-1740 \mathrm{~cm}^{-1}) with a resolution of (0.004 \mathrm{~cm}^{-1} ; 2036) transitions have been assigned in this hybrid type (A) and (B) band centered at (1688.3629 \pm 0.0002 \mathrm{~cm}^{-1}). The assigned transitions have been fitted to give nine rovibrational constants for the (v{2}=1) state with a standard deviation of (0.00064 \mathrm{~cm}^{-1}). The ratio of the transition moments, (\left|\mu_{b} / \mu_{a}\right|), has been found to be (1.98 \pm 0.10) for the band. 1994 Academic Press, Inc.
