The pressure dependence of the photodissociation quantum yield of acetone has been determined in different buffer gases at 308 nm. Results by Stern-Volmer analyses are in accordance with a suggested photolysis mechanism. Luminescence spectra, lifetimes and transition dipole moments have been determined. The energy transfer process by O2 to give O2( 1Δg) is of minor importance in the case of the singlet excited state of acetone, while it is the dominant deactivation process for the triplet state.
