PERRIN, Laboratoire Inter Universitaire des Systemes Atmosphériques, CNRS, Université Paris 12, 61 Av du General de Gaulle, 94010 Créteil Cedex France; H. BECKERS, H. WILLNER, Anorg. Chemistry, University of Wuppertal, D-42119 Wuppertal, GERMANY.

The infrared spectrum of DNO₃ (deuterated nitric acid) was recorded at high resolution (0.0018 cm ^-1) in the 800 -1400 cm ^-1 region on the Bruker IFR 120 HR Fourier transform spectrometer of Wuppertal. The analysis of the ₅ A-type band of DNO₃ centered at 887.656 cm ^-1 was performed taking use of the ground state parameters achieved by Drouin et al. . This band is perturbed by several resonances.
