science-softCon uv/vis+ spectra data base; www.uv-spectra.de; (C) science-softCon 2010 Substance: nitric acid Other Names: Formula: HNO3 CAS-No.: Study: uv absorption cross sections, photolysis, quantum yields Authors: H. S. Johnston, R. Graham Title: Photochemistry of NOx and HNOx compounds Journal/Source: Can. J. Chem., 52, 1415-1423, (1975) Data: (diagram, table, disk): diagram, table Energy/Wavelength range: 190 - 325 nm Resolution: Temperature: 298 K Temperature dependence: Pressure/Concentration: Phase (gas, liquid, solid): pH: Comments: Cross sections for absorption of radiation between 190 and 700 nm are given for N2O, NO2, NO3, N2O4, N3O5, HNO2, and HNO3. The quantum yields and the primary products of photolysis of each of these substances are discussed. Author to whom correspondence should be addressed: (e-mail address):
