Comments: The authors present the high resolution absorption measurements of gaseous HONO at room temperature 
using continuous-wave cavity ring-down spectroscopy in the near-infrared region between 6017 and 6067 cm-1 at a 
resolution of 1 pm (0.037 cm-1).
The measured and the calculated spectra are presented.
