Barney, L.M. Wingen, M.J. Lakin, T. Brauers, J. Stutz, B.J. Finlayson-Pitts Title: Infrared Absorption Cross-Section Measurements for Nitrous Acid (HONO) at Room Temperature Journal/Source: J. Phys. Chem. A, 104, 1692-1699, (2000); https://doi.org/10.1021/jp9930503 Data: table, diagram Energy/Wavelength range: 1263 cm-1; 852 cm-1; 790 cm-1 Resolution: Temperature: 294 - 297 K Temperature dependence: Pressure/Concentration: 750 Torr (total pressure in N2) Phase: gas pH: Comments: 750 Torr total pressure in N2. Both Q-branch intensities and integrated absorbances for the HONO modes trans-ny3 (1263 cm-1), cis-ny4 (852 cm-1), and trans-ny4 (790 cm-1) are reported.
