science-softCon uv/vis+ spectra data base; www.uv-spectra.de, (C) science-softCon 2012 Substance: Sodium superoxide Other Names: Formula: NaO2 CAS-No.: 12034-12-7 Study: uv absorption cross section Authors: B. Rajasekhar, J. M. C. Plane, L. Bartolotti Title: Determination of the absolute photolysis cross section of sodium superoxide at 230 K: evidence for the formation of sodium tetroxide in the gas phase Journal/Source: J. Phys. Chem., 93 (21), 7399-7404, (1989); DOI: 10.1021/j100358a030 Data: (diagram, table, disk): table Energy/Wavelength range: 193 nm; 248 nm; 308 nm Resolution: Temperature: 230 K Temperature dependence: Pressure/Concentration: Phase (gas, liquid, solid): pH: Comments: The absolute cross section for the photodissociation process NaO2 + hv --> Na + O2 has been measured at 230 K. The matrix-isolated UV absorption spectrum of NaO2 shows absorption maxima at 163, 248, and 309 nm. Author to whom correspondence should be addressed: (e-mail address):
