Abstract

The first measurements of near-infrared bands of deuterated nitrous acid (DONO) are presented. The measurements were made using Fourier-Transform Incoherent Broad-Band Cavity-Enhanced Absorption Spectroscopy (FT-IBBCEAS) in the 5800–7800 cm⁻¹ region. Two bands of trans-DONO centred at 6212.029 and 7692.496 cm⁻¹ were observed and assigned to the 2ν₁+ν₃ combination and 3ν₁ overtone vibrations, respectively. Their rotational band structure was satisfactorily reproduced using PGOPHER. For cis-DONO the 3ν₁ band was observed at ~7302.5 cm⁻¹. In addition, new bands centred at 6142.5 cm⁻¹ and 7607.6 cm⁻¹ were quite confidently assigned to the 2ν₁+ν₃ and 3ν₁ vibrations of deuterated nitric acid, DNO₃, respectively.
