science-softCon uv/vis+ photochemistry database; www.photochemistry.org; (C) science-softCon 2019 Substance: nitrogen trioxide Other Names: Formula: NO3 CAS-No.: 12033-49-7 Study: photochemistry, photolysis, quantum yields, absorption cross sections Authors: R.A. Graham; H.S. Johnston Title: The Photochemistry of NO3 and the Kinetics of the N2O5 - O3 System Journal/Source: J. Phys. Chem., 82, 254-268, (1978); DOI: 10.1021/j100492a002 Data: table, diagram Energy/Wavelength range: 450 - 680 nm Resolution: Temperature: 298 K Temperature dependence: no Pressure/Concentration: Phase: gas pH: Comments: UV-vis or IR absorption cross sections were measured for N2O5, HNO3, NO2, and NO3. At 1 atm total pressure, the photolysis of NO3 occurs with a primary quantum yield less than one in the red redion of the spectrum. Author to whom correspondence should be addressed: (e-mail address):
