Title: Wavelength dependence of the primary photodissociation processes in acetone photolysis

Journal/Source: J. Phys. Chem., 95  (26), 10816-10823, (1991); DOI: 10.1021/j100179a053


Data: (diagram, table, disk): 

Energy/Wavelength range: 285, 300, 313 nm

Resolution: 

Temperature: 298 K

Temperature dependence: 

Pressure/Concentration: 


Comments: Two primary photodecomposition modes are assumed:
CH3COCH3* --> CH3 + CH3CO# (hot) followed by CH3CO# --> CH3 + CO (1)
CH3COCH3* --> CH3 + CH3CO (2)
The low pressure quantum yields of these processes (Phi1; Phi2) are estimated as being equal to
0.10 and 0.90 at 285 nm, 0.06 and 0.94 at 300 nm and 0.03 and 0.28 at 313 nm.
