science-softCon uv/vis+ photochemistry database; www.photochemistry.org; (C) science-softCon 2019 Substance: sodium nitrite Other Names: Formula: NaNO2 CAS-No.: 7632-00-0 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: diagram, table Energy/Wavelength range: ~ 250 - 420 nm Resolution: Temperature: Temperature dependence: Pressure/Concentration: 0.02-0.06 M Phase: aqueous solution pH: Comments: UV-vis spectra of NaNO2 dissolved in aqueous solution (concentration range, 0.02-0.06 M) were recorded. The nitrite ion displays three distinct regions of absorption: two weak, broad bands with maxima at 354 and 290 nm and one very strong band with a maximum below 250 nm.
