Yamano, A. Yabushita, M. Kawasaki, A. Perrin Title: Absorption spectrum of nitrous acid for the v1+2v3 band studied with continuous-wave cavity ring-down spectroscopy and theoretical calculations Journal/Source: J. Quant. Spectr. Rad. Transfer, 111, 45-51, (2010); doi:10.1016/j.jqsrt.2009.07.009 Data: table, diagram Energy/Wavelength range: 6017 - 6067 cm-1 Resolution: 1 pm Temperature: 298 K Temperature dependence: no Pressure/Concentration: Phase: gas pH: 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. Author to whom correspondence should be addressed: (e-mail address):
