science-softCon uv/vis+ photochemistry database; www.photochemistry.org; (C) science-softCon 2019 Substance: nitrous acid Other Names: Formula: HONO CAS-No.: 7782-77-6 Study: uv absorption spectra Authors: E. Riordan, N. Minogue, D. Healy, P. O'Driscoll, J.R. Sodeau Title: Spectroscopic and Optimization Modeling Study of Nitrous Acid in Aqueous Solution Journal/Source: J. Phys. Chem. A, 109 (5), 779-786, (2005); DOI: 10.1021/jp040269v Data: table, diagram Energy/Wavelength range: 270 - 400 nm Resolution: Temperature: Temperature dependence: Pressure/Concentration: Phase: aqueous solution pH: Comments: The molar decadic absorption coefficients are measured. For HONO, the wavelength maximum for the strongest vibronic band in solution was found at 372 nm with an epsilon value of 60.52 ± 0.6 M-1 cm-1.
