Romero, M.A. Blitz, D.E. Heard, M.J. Pilling, B. Price, P.W. Seakins, L. Wang Title: Photolysis of methylethyl, diethyl and methylvinyl ketones and their role in the atmospheric HOx budget Journal/Source: Faraday Discuss., 130, 73 - 88, (2005); DOI: 10.1039/b419160a Data: Energy/Wavelength range: 308 nm, 320 nm Resolution: Temperature: 213 - 295 K Temperature dependence: yes Pressure/Concentration: Phase: gas pH: Comments: Quantum yields for acyl (RCO) radical production from ketone photolysis as a function of temperature, pressure and the atmospherically relevant wavelengths (308 and 320 nm) have been determined for methylethyl ketone (MEK), methylvinyl ketone (MVK) and diethyl ketone (DEK).
