Journal/Source: Chem. Phys. Lett., 440, 31-35, (2007); doi:10.1016/j.cplett.2007.04.014


Data: (diagram, table, disk): table, diagram

Energy/Wavelength range: 248 nm; 308 nm

Resolution: 

Temperature: 233 - 323 K

Temperature dependence: 

Pressure/Concentration: 13 - 998 mbar


Comments: Exciplex laser photolysis at 248 and 308 nm wavelengths coupled with gas-chromatographic analysis was 
applied to determine the photodissociation quantum yield of acetone (QY). At 308 nm, QY has been found to decrease 
with decreasing temperature (T = 323-233 K) and to decrease with increasing pressure (P = 13-998 mbar synthetic air).
