Scientific paper

Nitrous acid is an important species in the atmosphere of the Earth since it is a significant daytime source of OH radicals, known to play an important role in tropospheric ozone formation. It is also a molecule of interest for molecular dynamics and ab-initio calculations. In this work, relative line intensities of trans- and cis-HONO and DONO have been measured using absorption spectra in the far-infrared previously recorded by high-resolution Fourier-transform spectroscopy. These relative line intensities measurements were fitted in a least-squared procedure leading to the determination of the b-component of the permanent dipole moments for those species and their rotational corrections. Scaling those values to the absolute values derived from Stark effect measurements allowed us to re-determine the energy difference between the two isomers (Δ EHONO) to be 107±26 cm-1. This value is in good agreement with previous experimental studies calculations and with recent high-level ab-initio calculations.
