Gorrotxategi Carbajo, A. J. Orr-Ewing Title: NO2 quantum yields from ultraviolet photodissociation of methyl and isopropyl nitrate Journal/Source: Phys. Chem. Chem. Phys., 12, 6084-6091, (2010); DOI: 10.1039/C001425G Data: (diagram, table, disk): table Energy/Wavelength range: 308 - 320 nm Resolution: Temperature: 294 K Temperature dependence: Pressure/Concentration: 7.5 - 12 Torr (partial pressure of isopropyl nitrate); total pressure 200, 500, 700 Torr (N2) Phase (gas, liquid, solid): Comments: Photodissociation quantum yields, PHI(NO2), were measured to be unity (with <10% uncertainties (2SD)) for both methyl and isopropyl nitrate at wavelengths of 308, 315 and 320 nm in the presence of N2 bath gas at pressures up to 700 Torr, and at a temperature of 294 K.
