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: W.J. Marinelli, D.M. Swanson, H.S. Johnston Title: Absorption Cross Sections and Line Shapes for the NO3 (0-0) Band Journal/Source: J. Chem. Phys., 76, 2864-2870, (1982); http://link.aip.org/link/doi/10.1063/1.443366 Data: table, diagram Energy/Wavelength range: 654 - 670 nm Resolution: 0.05 nm (FWHM) Temperature: 298 K Temperature dependence: no Pressure/Concentration: Phase: gas pH: Comments: The absorption cross section of the nitrate free radical has been scanned by a tunable dye laser with 0.05 nm resolution (FWHM) between 613 and 672 nm. These data, combined with other recent measurements, give a peak cross section at 661.9 nm of 1.90×10-17 cm2; and the integrated cross section over the 0–0 band from 14910 to 15290 cm-1 is 2.02×10-15 cm.
