New bands of deuterated nitrous acid (DONO) in the near-infrared using FT-IBBCEAS

Raghunandan, R.; Orphal, J.; Ruth, A. A.

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 2ν$_{1}$+ν$_{3}$ combination and 3ν$_{1}$ overtone vibrations, respectively. Their rotational band structure was satisfactorily reproduced using PGOPHER. For cis-DONO the 3ν$_{1}$ 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 2ν$_{1}$+ν$_{3}$ and 3ν$_{1}$ vibrations of deuterated nitric acid, DNO$_{3}$, respectively.
