Title: Study of Acetone Photodissociation over the Wavelength Range 248-330 nm: Evidence of a Mechanism 
Involving Both the Singlet and Triplet Excited States

Journal: J. Phys. Chem. A, 110 (21), 6742 -6756, (2006); 10.1021/jp056276g S1089-5639(05)06276-6


Data: (diagram, table, disk): 

Wavelength range: 238 - 330 nm

Resolution: 

Temperature: 218 - 295 K

Temperature dependence: 

Pressure: 0.3 - 400 Torr

Comments: Measurements of the acetyl yield from acetone photolysis have been made using laser flash photolysis/laser 
induced fluorescence. PHI total(lambda,p,T) was determined over the ranges: 266  lambda/nm  327.5, 0.3  p/Torr  400 and 218  T/K  295.
