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.
